The regex support you currently have doesn't really allow for complex (multi-match) regex matching, which is probably ok. (this would be something like grep -e 'this' -e 'that')

If I select, say 116 of the 124 metadata types identified, and then have to apply a regex pattern to each one, it gets pretty tedious. Click-paste-apply 116 times, and then 116 again for the other half of the complex match. I'd write a tool to automate configuring a filter in gearset. :)

If I "select all" then deselect the 8 types i don't want, and THEN apply a regex to all types, that would be pretty great.
