Rated 5 out of 5 stars

This is a great add-on which completely changed the way I browse.

I have a small feature request (apologies for posting this in a review, but the support email address seems to be invalid, the server returned: 511 sorry, no mailbox here by that name / skrzynka pocztowa odbiorcy nie istnieje (#5.1.1 - vuser)).

I have one small pet-peeve regarding the Grab and Drag feature.
Is there any way to have an option to reverse the direction?
E.g. dragging upwards scrolls *down* rather than *up*, such that the
pixel on the page under the mouse pointer does not change. This will
be more familiar to Mac OSX users and Linux GNOME users with the
"natural scrolling" option turned on.

If this is not an option you'd consider adding, could you if possible
provide me with a patch/diff I could apply to the source files to
directly reverse the direction? Or maybe some hints on where to
look so I can try my hand at a dirty hack. :)

Thank you for your great work!

Edit (reply to the developer): Yes the acrobat reader setting does exactly what I want. Can't believe I didn't try it before. I guess I wasn't sure what it meant, so I just left it alone. Thank you!

This review is for a previous version of the add-on (1.7.0.1-signed). 

Sorry about the invalid email address - I was just moving server yesterday so it was not set up again immediately. It should be working now, though.

As to the Grab and Drag scrolling direction - go to Advanced Prefs #2 and turn on Acrobat Reader mode and see if it does what you want.
