I sort of use RAW as my back up, but use JPEG as my go to file, to browse and to share. JPEG are on slot 2, but the rear viewer always defaults to slot 1. I like to select by default which card is the default for the rear display.
Geolocations - it needs an option to forget a location rather than menu digging or letting it time out. Basically a reset location option in the quick menu.
Delete JPEG and RAW File associated with it option.
In camera raw editing needs a micro adjustment/degree rotate on the rotate option. Just to straighten photos.
They also need to do some work on Camera remote, after any action you have to reconnect.
