It would be nice to have some easy way to disable language server handling for files / projects without the need to do this inside the settings (and likely forget to re-enable it again)

Special stuff can lead to lots of complains which may end up in polluting a file (open e.g. QC's squish stuff) - disabling some of the annotations help temporarily, but is a bit cumbersome.

It would be nice to have something inside the editor toolbar (some action inside the LS tool button, similar to the restart functionality)
