The following tag sidebar order modes could be added:
- Most used tags first
- Manual (custom) order
This assumes introducing some UI control that allows to toggle ordering mode.
Sorting tags by count was also suggested here:
Manual order allows me to arrange tags in the order I like by dragging them in the sidebar. This order is saved, and even if I switch to alphabetical order and then back to custom order, my custom order is preserved.
