Same for the bookmark/comments panel. There should be an option in settings that gives the user control over these panes opening or not automatically when a file is opened.

the rite panel stay away if u select "remember current state of tool panel"

u just need to make it that selecting this will allso remember the status of the left panel and the comment panel

While we're at it, I never EVER want to see Comments, it's the most intrusive annoying feature I've ever seen. I've never used any of the 'tools' It's a GD reader for F sake, just let me read my stuff with out all these windows that shrink my document down to the size of an icon.
