Can you please add "Open All in Tabs" button to folders (in addition to 3 existing buttons: edit URL, reload, remove), as in the Bookmarks menu? And this button should be visible always (i.e. not affected by "Show dial edit buttons only with 'gear'" option).
You can just use Ctrl+Left Mouse Click on folders for open all in tabs. I don't think what this is would be good change because it may lead to accidentally opening all bookmarks.
