A couple of suggestions:

1. Please, please, please add the CMYK colour profile! I'm an illustrator and publishers & art licensing companies want their files delivered in CMYK. PS has the facility but if it was added to Artstudio Pro it would mean that I could ditch PS altogether (and that subscription!). 

2. Also, it'd be great if when I've exported a file in .psd format that I could then click save as I'm working instead of having to re-export it.
