brilliant productivity enhancer, best replacement for tab groups that's available now.
I'd love it if
- the colours were a little more muted,
- I could edit a group name from the initial drop down menu,
- it was quicker to delete the auto created groups on new window - it's noisy, and deleting them is quite a few clicks
(delete + undo would be better than delete and confirm, delete from initial popdown would be a click saver)

otherwise, awesome.
