Sometimes things break. When those things break, it might be because of errors in several different places with different logs on different hosts. It would be great if I could group (and even collapse the groups when not using them!) the log files into categories or labels so I can easily pull up the logs relevant to the issue at hand.

For example, if I have three servers A, B, and C that together do two tasks 1 and 2, they would each write their own log file for each task. So if servers A and B work on task 1, the would have `serverA_task1.log` and `serverB_task1.log`, and similar for task 2 that runs on B and C.

If task 1 fails, I would like to be able to look at the group of log files that task: `serverA_task1.log` and `serverB_task1.log`, and possibly collapse or hide the other log files for the current time. I could combine them into a single log, but that can make it more challenging to follow the exact process that each server was doing.

(Similarly, a different feature that is related: it could be great to have temporary merged logs by just selecting multiple log files in the side bar.)
