Rated 5 out of 5 stars

Excellent! Fits with my mail reading habits very well. The little navigation toolbar is also nice, given that the default Thunderbird "Back" and "Forward" don't behave (IMO) intuitively. Would be great if it could also search into collapsed threads ..

Perfect with Lightning Rated 5 out of 5 stars

This extension is exactly what I need. I use another extension called Lightning that adds a "Today Pane" on the right side of Thunderbird (after version 0.7 of Lightning is released), so there is less room on the screen to read my emails. Maximize Message Pane solves this problem because it lets me hide the Folder Pane for certain emails by simply clicking on the toolbar button. Nice.

Attachment pane Rated 4 out of 5 stars

No matter what option I use, it doesn't collapse attachment pane. Otherwise, very nice add-on.
