Version 0.9.9.1:
(*) Fixed bug where Adding Mail Reminders wasn't working in Thunderbird.

Version 0.9.9:
New features:
(*) New Lists! In addition to reminders and ToDo's, you can add additional lists that will show up as separate tabs. You could keep lists like: Movies (for upcoming movie releases), Albums (for upcoming music releases), Groceries (to keep track of items you need), or anything else that you can use a list for. This is good for list-oriented people like myself :) You can add/reorder your lists from within the Options.

(*) There is a new preference option to hide completed items. In addition, there is also a context menu in the edit window to temporary show or hide completed items.

(*) You can now set dates on ToDo and List items. ToDo's with Dates will show up in your tooltip just like Upcoming Reminders. You can also now set alarms for ToDo and List items. (The Date column is hidden by default for ToDo's)

(*) Reminders and ToDos now store the date that you completed the item. (The Date Completed column is hidden by default)

(*) You can now move reminders to any list via the Move to List context menu item. Also, you can move any ToDos or List items (that have dates) to the Reminders list.

Improvements:
(*) Automatically Synchronizing to a network has been greatly improved. Synchronization now happens in the background; when you bring up the Edit Reminders window, the synchronization status is displayed at the bottom of the screen instead of a small modal window. Similarly, after you close your Edit Reminder window, your reminders are uploaded in the background so you no longer have to wait for this operation to complete.
(*) Better column interaction. You can now click directly on columns to toggle Complete state, Remind Until Complete and Show In Tooltip status. You can also click on a reminder's email icon to view its associated email.

(*) Column headers now show icons for Mail, Completed, Show in Tooltip, and Remind Until Complete. It was difficult to really identify the columns with just the text, and now the column size can be much smaller

(*) Now when you mark a repeating reminder as complete, it will only mark that instance (and previous instances) so that future occurrences are not marked as well.

(*) Notes now show up in alarms.

(*) (SeaMonkey) Fixed some bugs to now work properly in SeaMonkey/Mozilla. Thanks to Philip Chee.

(*) (Thunderbird) The Add a Reminder menu is now available when selecting any message in the message list, as well as the message and preview panes. Thanks to Guenter Wahl.

Bug fixes:
(*) If the preference is set to show no past occurrences, the list wasn't showing reminders set to Remind Until Completed

(*) fixed bug where alert could still possibly show if it had been marked complete since last alert

(*) fixed bug where alert could close when you closed the Reminder List window

(*) fixed bug where Importing from network would fail if the remote file was not created by ReminderFox.

(*) fixed bug 14783 - Upload window with status "sending" stays open (ftp)

(*) fixed bug 14784 - duplicate alerts could show multiple times

0.9.8:
(*) Thunderbird Integration:
(-) From Thunderbird, you can add a reminder for any message that you view. From the message pane, right-click and select Add a Reminder from the context menu. This will allow you to add a reminder for that email so that you can be reminded to look at it again at a later date. (Note that the context menu option is only available from the message pane and preview pane; it is not yet available on the message list view context menu, but we're working on it.)

(-) You can add a reminder for any message inside of Thunderbird, be it an email from any account, an rss feed message, a news group message, etc.

(-) When viewing your reminders in the ReminderFox list, all of the reminders that are associated with an email are indicated by a small mail icon in the Mail column. (This column is hidden by default, but can be made visible by clicking on the twisty at the top right-hand side of the reminder columns.)

(-) From ReminderFox, for any reminder that is associated with an email, you can right-click and select View Mail from the context menu. This will retrieve and display the associated message.

(-) Thanks to Guenter Wahl and Markus Hossner for their contributions to get Thunderbird integration working.

Minor improvements:
(*) You can now search for ToDos just like reminders (via the Find context menu or shortcut key)

Bug fixes:
(*) Now only shows an alarm if reminder has not been marked complete or deleted
(*) Fixed extension conflict with ProfilePassword
(*) Now properly shows number of repeating upcoming reminders in the tooltip according to preferences (it was showing an additional repeating instance)

(*) Hide repeating reminder occurrences. There is a new preferences that allows you to specify how many previous ocurrences and upcoming occurrences should be displayed in the list of reminders
(*) Option on Edit Reminders window context menu that lets you toggle between showing all and showing no repeating instances in the list

Minor improvements:
(*) When you snooze an alarm, the last snooze time is remembered the next time you are alerted

(*) Fixed bug #13647 - reminderfox is not displayed in Thunderbird on startup (when using synchronization with network)
(*) Fixed problem where wasn't showing some missed alarms

(*) You can now add Notes to reminders and ToDo's. Click the note icon in the Add Reminder/ToDo window to add additional notes to a reminder. You can also view notes in the Edit Reminders list by hovering over a reminder or ToDo item.
(*) You can now mark ToDo's as Complete. This will check the ToDo as complete and strike a line through it but will leave the ToDo in your list. (You can use the spacebar as a keyboard shortcut to toggle a ToDo or reminder as complete).
(*) New icons to denote reminder and ToDo properties. In the Edit Reminders list, if you show the various propery columns (click the column picker icon to the right of the column headers to choose columns), they will appear as various icons to make it easier to distinguish properties:
-- a note icon signifies that a reminder or ToDo has a note attached to it
-- a ribbon icon signifies that a reminder is marked to Remind Until Complete. A blue ribbon signifies that the reminder is marked but the date has not yet been reached. A red ribbon indicates that the reminder is past the original date.
(*) New ReminderFox Icon - thanks to Ricardo Ortiz!

Minor improvements:
(*) Added some keyboard shortcut identifiers

Bug fixes:
(*) Now sort reminders that occur on the same day chronologically by time
