A common request/concern from new users is:

"Wait, if I use Tagger, like you recommend, I have to click on EVERY new performer/studio/tag to add them? That will take forever, and I don't want to do that. Don't you guys have a setting to just auto add?"

Alternatives like using Identify (which can auto create, but fail to add images/etc), also fail to allow any sort of manual checking... it's basically "all or nothing".

If a "Create All" button/option is added to Tagger, most of this resistance will go away. While there is a userscript that add 'save all' as an option, the stock app would retain the relative safety of still requiring someone to manually review, but allow them to not have to hit 'create' (and then confirm/save, so 2 clicks, plus load time) for each new performer/studio and each new tag.

Either a button (Create Missing? Create All?) or a set of options ("Create Missing Performers, Create Missing Studios, Create Missing Tags") would be good, but I'd favor the latter, as allowing partial automation... Someone might not want new tags, for example.
