Hi! Thanks for developing this; at this point (with tab hide functionality), it functions almost as well for me as Tab Groups did before, and this is what actually prompted me to upgrade to quantum. But there is one pet peeve of mine that is hopefully not too hard to fix. I middle-click on my bookmarks toolbar all the time, and new tabs with links from the toolbar always open in default container. Would it be possible to change it to be consistent with opening an empty new bar, which already happens in the container you're currently in (maybe not as default behavior, but as an option)? Also, would it be possible to have the container drop-down menu that is sorted in any other way than alphabetically?

Edited, since I guess one can't post answers to dev comments. :-)

Edit: well, I guess ideally one could arrange the containers in the list by hand, through drag-and-drop or any other way, but even the order they are in about:preferences#containers (which is, I guess, the order of their creation) would be fine to have.
