The tagging system needs to be reworked.
allowing symbols (. , etc) when typing to tag someone.
showing users with badges first.
scrollable list of users to tag.
faster loading time.
remove the glitch when typing. -half the time it doesn't update the list and you have to delete what you've typed and retype it.
This happened to come up in the Corvid Forum earlier, so just thought I'd post it here as well.
