I'd love to be able to declutter the "Problems" Markers Panel by hiding/showing logs generated by only certain extensions.

Right now, if I type [ts] into the filtering box, I get No results found with provided filter criteria. Clear Filter.

If I then delete the filter, I can clearly see plenty of warnings and errors generated by [ts]. After tinkering with it for a while, I've not been able to figure out how to filter by the extension name. (Maybe it just needs some documentation or UI to help the user write filters?)

Also, for other users finding this issue, after a bit of searching around I realized I could also filter roughly by using the keywords warning, error, and info. E.g: enter warning, error into the filter to hide info markers. This helps a bit, but doesn't help much when you're trying e.g. to filter out a particularly noisy extension (like a spell checker) generating the same type of marker you're looking for.
