I feel that it would be quite useful, for troubleshooting purposes, if the icon that displays the undervoltage / overheated state in the top bar of OctoPrint would also show some indicator of when the event happened in the hover-over display (provided the event is not ongoing).
I realize that this information can be found in the octoprint.log file, but having the data available at a glace would be a great QoL feature, which could help people with intermittent issues determine the cause of those issues.
I have some apprentice-level coding skills, but wouldn't really know where to start insofar as coding a plugin is concerned. Perhaps one already exists, but I've been unable to find it. It seems that perhaps a modification to the Pi Support Plugin could add this info without much fuss, but I'm certainly speculating, there.
Please forgive me if this has already been covered! I tried searching the forum but didn't come across anything that seemed right.
