A good effort, still plagued by the bad user interface and some stupid limitations.
WE WANT TO MOVE TABS AROUND! I understand it might not be possible the old Tab Groups way. Still, you can make it possible (now is almost prohibited) by this sooo simple tweak:
MAKE THE TAB URLS EDITABLE AND ADD A "NEW TAB" FUNCTION at the Edit group tab and we will simply COPY-PASTE THE URLS without having to leave the active tab group. IT IS THAT SIMPLE!!!!
Also, it would be nice if you made possible a scheduled Export function, we wouldn't fear that we could lose our tab groups for some weird reason.
