I was playing with the cool tags at moodle.org when I've experienced one annoying (subjective) behavior. Just sharing it here:
When adding tags I wanted to introduce them in order, i.e. if "Education" is more important (for me) than "Macs" I use to write them in that order and want to show my tags (user profle) respecting that order.
But it seems that the order is completely lost, mixing them without apparent order (both when displayed and when re-edited in the profile page).
I really think that a lot of people can find this (subjectively) annoying and they want their original order to be respected.
Just one (simple?) idea.
