One minor suggestion: Would be great if the (per-database) Inbox group could appear at the start of the list of groups, rather than in the normal alphabetic position. This would make it much easier to locate when switching between databases (as I often do when sorting). The same with the “Tags” group.
Minor, but would really help with some of my workflows
If Sort is set to Unsorted, then you can move the Inbox, Tags group, and anything else to wherever you want in the database. Just drag them back to the top and they should stay there.
