shift and click jobs to select many at once, then delete the job. Things can get messy and it’s annoying to have to delete jobs 1 by 1.
Similarly (but less important) a tool to delete all incomplete jobs (failed jobs, building jobs, etc).
Just stuff to keep things tidy. Also maybe some way to figure out which stack your jobs are drawing on. The tree is kinda less than ideal, and tracking through prev jobs to find the source stack is a bit tedious.
