Apologies for having posted similarly in Support, but this does seem a feature.

For those who might be using a (non-airmouse) remote, just the ability to use the cursor keys and ok/select to move thru the interface.

It works well as is with the indexers section and nzbget, but with sonarr some elements can't be reached this way ;(

(But that it can work this way well enough is a pleasant surprise, as I appreciate the app probably wasn't intended to be used in this context.)
