KB is the maker of this program. 
Thereâs a âwishlistâ threadâsee this post for the etiquette, but in general, yes, Keith listens. He does not always agree, nor is it always possible to do what users suggest, but heâs nice about it.
Before posting your requests, though, definitely take some time to go through the tutorial project in Scrivener (Help>Interactive Tutorial) and to browse the forum for the topics you want to ask about. Someone may have already asked about the feature you want to request (repeats are unnecessary and â+1â is frowned upon and does nothing to help your case) and you might find a reply suggesting a good workaround or other tips.
Welcome to Scrivener!
EDIT: Augh, I wrote too slowly. Well anyway, you can report the error in the Bug Hunt forum.
No; just Scrivener 2.0 for the new Mac App store.
