No, I am sorry, you're not right. I have double checked with fresh install and surely visible panel, still does nothing. In fact it does not matter if plugin is installed or not. Absolutely no effect at all.

Toś ten wužywaŕ ma starše pógódnośenje toś togo dodanka.

What kind of OS do you use ? I tested addon on Windows and Linux. Do you see in Options addon number of saved messages or there is only zero ? Of course, the value indicates how many messages have been marked/displayed since the add-on was installed

Version 1.2 it is not functional in the version 115.16.2 (64bit). Version 2.0 cannot be installed because it is said to be incompatible with this version. So a stalemate.

Do you have enabled Message Pane (F8) ? Addon saves selected message after displaying its content, so the Message Pane should be visible.
Version 2.0 is for the current version of Thunderbird, which is version 128.

Can you give us an easier way to contact you? It doesn't work in Unified folder mode.

You have right. I don't use Unified Folders so I don't check this. I will try to find the solution. Thank you for your attention.

I give this 2* because of the premise -- it is a good idea. However, it simply does nothing that I can see.
