You can name them if you want.

Hah. I didn't even realize you could _not_ name them.

I just do:

    jj b c zellyn/appname-update-plugh-tests
    jj git push

jj git push -c <changeid> will create a bookmark for you and automatically give it a random name. Most folks who do this configure it to add a prefix, often a username.

Oh, I didn't know you could do that. Nice.
