Additionally, cancelling all builds would be nice.
I pushed --all, then --tags a checkout of ~sircmpwn/lists.sr.ht to ~nabijaczleweli/lists.sr.ht earlier, and this queued eight pages of builds, one for each tag; I obviously didn't intend this.
Fixed that particular problem by limiting the number of builds which git.sr.ht will submit at once.
While cancelling is possible from the particular job webpage, it would be awesome to have the "cancel" button for every job in the queue overview at https://builds.sr.ht/ - it's useful when cancelling some builds for old, now irrelevant commits.
