In PhpStorm how can I only show Errors, not Warnings globally for all files etc.?
I only can find the Inspection area in Preferences, but there I would have to uncheck all warnings, minor warnings for all Checkboxes and had to manage this for new file types in the future.
So, how can I Globally only show errors like it was possible in the past with Inspection Levels?
That can't be done in one click, but there's still a way. Open your inspections (File | Settings | Editor | Inspections), create a new inspections profile, e.g. "Errors only". Use filtering options to select all the inspection types but "Errors":
Then click on a top inspection name/group and then shift+click on a bottom one to select all of them:
Then press Space 2 times to remove all checkboxes. Save the profile. Voilà! You now have a "Errors only" profile that you can use for this project when needed.
