Still no bookmark integration? Rated 3 out of 5 stars
This would be great if it didn't use its own totally incompatible way of storing its bookmarks.
Why not just let the user choose a regular bookmark folder as root? (or several for the tabs).
Then you would get all the functionality that can be added to the bookmark system for free.
For example automatic synchronization via xmarks, or whatever the user has set up.
Seems like this should be prio one to implement.
