Can’t see running builds when there are too many errors

[emilazy]

If you’re masochistic enough to run huge builds to test out breaking changes like I am lately, the bottom pane can fill up with failed builds without showing the current status:

I think that past a certain number of failures it is more valuable to see ongoing progress than yet another failure. Perhaps it could show only the the most recent 10–20 failures or something.

By the way, thank you so much for this tool and for the Matrix bot; they’re life‐changing!

Sounds like a power user feature. :D

I only started using nix-output-monitor because nixpkgs-review defaults to it on the community builder so I might have a very non-representative set of build graphs I've put through it :)
