Great add-on. I installed it for that “tab in sidebar” feature. I think it would be perfect if it closed the tab after then.

EDIT: None of the options work in Linux

EDIT: Your descriptions about the preferences shows that I’ve been misunderstood. So sorry.

1. A narrow bar appears on the left side of window, even when the sidebar is closed. I thought unchecking the collapse should make it go. The collapsing option you explained works.

2. I thought the splitter is the narrow bar on the RIGHT side of the sidebar which splits the sidebar from the tab content. Changing the splitter values don’t have any effects on this.

The left-side splitter is OK, however its minimum size is 6 and actually doesn’t get smaller.

This review is for a previous version of the add-on (0.1.1.1-signed).

I can add an option for this:

I can't test on Linux right now, but are you sure?

Disable menu items for opened sidebars: should disables "Bookmarks" checkbox in the menu (will be displayed with gray text) while bookmarks opened in sidebar.
Collapse sidebar (instead of close): to reopen sidebar in the same state (but only in only in current session), e.g. open bookmarks and type something in "search" field, then close sidebar and open it again (with bookmarks, of course) to see the same state.
Splitter width (and splitter width in maximized window): just a width of the splitter in the left side of window.
