Tags in the commitfest app: How to use them and what tags to add?

I deployed support for the ability to use tags in the commitfest app a
few hours ago. How exactly we want to use them is up to the community
at this point, but that seems hard to align on without people trying a
few things out.

That's why I added some tags to the patches on my dashboard. It would
be great if others could do the same.

The tags that are currently available are some default ones that I
thought might be useful. If you're missing certain tags or don't like
the default ones, please respond to this thread. If you have the right
permissions, you can even create missing tags yourself in the admin
panel.^1 But if you do, I think it would be useful to post here which
ones you added for discussion purposes.

^1: I don't know who can do this, as I myself currently don't have
that permission, nor the permission to look at permissions...
