Sidebar Tabs

Love this tab group extension, tried most of the tab managers and this one just works, do have some small improvements I would like to see, but is better than the last 4 I tried, I am a heavy tab user and this sidebar with tab grouping is outstanding. Not sure how many tabs I have open but would say 300+, and being able to group by setting tab group labels is amazing. Suggestions for feature, ease of use improvements: Need to drag and drop multiple selected tabs, when I do it now, only moves one. Needs move to -> move to a named tab group Can't drag multiple tabs to a collapsed tab group, but can drag a single tab into an open tab group, should both work Can't grab and drag a collapsed tab group to a new location, but can open, select all the tabs, and move as a group, and then recreate tab group - cumbersome. When dragging into a named tab group, will only let you drop behind first tab in the group, not in front of that tab, and won't let you drop it after last tab, though the highlight line shows up as if you could.
