Version 1.2 of Quick Bookmarks introduces a few new features.
A third page was added to the popup dialogue listing all bookmarks from the workspaces. The selected bookmark list in the dialogue is now remembered even when restarting Eclipse.
Bookmarks store the editor type they were set in. For example, when opening an HTML file in a text editor and setting a bookmark, then reopening the same file in browser mode, jumping to the bookmark will jump to the text editor instead of the browser.
For installation instructions, please see here. As always, feedback is welcome.
