Feature request: Toggle minimum diagnostic severity for diagnostic picker

[nick42d]

When working on a branch with a large number of diagnostic warnings, errors can get drowned out. It would be nice to have a way of toggling this.

languages.toml diagnostic-severity is not suitable, as once I have tackled the errors I would like to toggle and move onto the warnings without editing configuration.

This would be solved by implementing fzf ORs operator. The last bit of fzf syntax we don't support yet. I have also found myself missing these for other applications. Then you could do $severity err|warn|info for example. I don't think adding a config option is something we would that. We are generally extremely conservative ablut adding config options.

For now, you should be able to enter %sev ERROR to filter that column. But this picker doesnt keep a history of what you entered so you would have to type it each time as you go through them.

that is the same thing I was saying but only works for error but not for warnings for example (issue is about minimum severisyt not about just showing a single severity). I don't think manually typing a couple of characters into the picker is something that needs a config option

Cheers both! Learned some things from this;

• There are some fzf-like matching options for the picker Add optional substring matching for picker #5114.
• On master the picker is now column based Pickers "v2" #9647 (I was running Arch latest 24.03) and typing %s ERR will show only errors.
• There is a docs PR for some of this functionality open here: Document use of filter columns in pickers #11218.

From my perspective this covers my use case for now. I would generally just want to see errors only or all diagnostics. I will see if I can contribute to the docs PR at all.
