Most of my workflow (and the team which I'm part of) resolves around the command
line, but arc is a little lacking on the options it supports for some commands.

I've written a couple of patches to add some of the missing flags I need, like:

• Add flags in arc list to filter diffs by reviewer and/or author
• Add flag in arc todo to add a priority on the newly created task

Tasks T7787 and T7715 seem relevant with the above.

If the above sound useful for more people and you're willing to accept the
patches, let me know and I'll send them for review.
