Focus the editor you'd like to focus. This can be an output channel as well.
Run one of these commands:
"Filter Active Editor"
"Filter Active Editor In Place"
"Filter and Watch Active Editor"
Only supported for output channels for now
It will only be watched as long as the output channel is visible. The TextDocument is disposed when the output channel is closed, so there is nothing for us to watch.
Future work
Regex patterns
Show patterns in a tree view
Enable dynamic enabling/disabling of patterns, auto-updating the filtered content
Hint the number of filtered lines, maybe with an editor annotation or codelens. "x lines filtered, click to show". Or a folding range provider
