Log Filtering
### Feature Description

This has been brought up a bunch of times but they're all stale. 

Hopefully this isn't a hard feature to implement, and the value is huge during debugging sessions.

Filtering two ways would be sweet:
1) Custom string in a text box
2) Click on any plugin title on its log line, then use that title for filtering (populate it in the text box)

Thanks!
