Great extension! I wish I could use my own uploaded icons and choose from a wider range of colors instead of the limited options provided. Additionally, due to the limited color choices, it's difficult to determine if a container is the one I need, and the other options don't work as well. I would appreciate a small title, similar to the bottom of spreadsheet tabs, overlaid on the icon color. We have Retina and 2K+ displays. Also, opening up a new container always in it's own window too could be helpful. ie research window next to wasting time window, etc without pulling tabs off to separate. Thanks, y'all!
