There is a crash issue
There also was issue that plugin was in English instead of inRussian (how was Opera, Windows and stand-alone PDf Xchange Viewer)
And there was dialog-too-high issue
And one more.
Either occasionally or intentionally but forgotten - all the panels be hidden.
And if one does not remember hotkeys F9 and F11 - there seems no way to come out of it
Just remember how MS Office 2003 implemented special toolbar with only button "close print preview" ? they probably also had similar issue
So what i ask for. In minimal mode of plugin, the only part of UI that is not either browser or document itself, seems to be "papersize" indicator in bottom left corner.
When user right-click onto it it would show some menu.
I ask that:
1) this menu also could be called by left-clicking, not only right-clicking.
2) this menu at top contained actions "Show main menu (F9)" and "Show toolbars (F11)", maybe always or maybe when Main menu / panels were hidden before.
There should be way for mouse-only newb user to recover the hidden panels
