improved Bookmark functionality
This may be due to limitations in the VS Code API, but it would be nice if the Bookmark Explorer had more intuitive features. I would expect to be able to right-click and rename groups and queries, or drag and drop to re-order them. It would be nice to be able to drag from the History buffer to create a bookmark that way.
I'm not sure if the Bookmark metadata is just for internal tracking, but I'm not able to apply any changes to that. Unless I'm missing something Bookmarks seem immutable and you have to create a new one and delete the old one in order to make any persistent changes.
Nice-to-have: ability to sort by group name

+1
I know this is an older thread, but I'd like to add that it would be nice to bookmark tables as well. I regularly deal with a database with hundreds of them.
