OK, maybe now I'm done spamming feature suggestions. ;) But the extension is already helpful how it is, thanks for making it!

While you're at it, perhaps add a toggle to filter usernames containing filtered tags. Maybe automatically treat tags as a wildcard when filtering usernames for them, since usernames don't typically have spaces in them. I suppose for tags that could be part of another irrelevant word, that could pose an issue, though.
