Exporting layer options

The one thing that I really wish was incorporated is how PNGS for example are exported. I want to be able to export selected images as a png instead of the whole layer this saves me the time of having to open up that image then and crop it. Having the option in a dropdown with layer, whole canvas, and selected objects would be amazing and save me so much time in the cropping step of my digital creations.
Please make these changes… it would really change the game with this app.

+1 on export selected object(s) as a trimmed PNG with transparent background.
