The list of interesting tags would be more usable if it was ordered alphabetically.
Apologies if this suggestion has already been made, I couldn't find it (this is the closest, but not quite the same).
Alphabetical sorting should be the default, because it makes it easy to find the tags you're looking for.
As Adam suggests, there could be a switch to disable the automatic sorting, and possibly even a method to easily re-order the list and save that custom order.
Adam's manual sort sounds like a really, really ugly work-around, but one that works well. Still, it can't be the intended use -- if there's a new tag created which is very interesting to me, I would have to delete every single tag and re-add them all again, manually. Surely a more elegant solution can be provided.
If this is implemented, it should be an optional feature, not automatic. I have my interesting tags sorted in more-or-less the order I want them, more interesting first, even though I had to delete and re-add tags to get it that way.
