three ideas: 1) a square eraser tool. 2) the ability to undo just your last erase (for accidental touches) 3) the ability to erase all of one color from a layer. ex. use a dropper - pick a color.

cool app I'm having fun with it. the layers stop after 4 right? maybe the ability to add more layers would be nice? last question, what does the erase thing do on the erase screen. pencil, brush, eraser that I can't quite figure out. thanks

I can't download layer packs as it show -error establishing a database connection. Also  when I tried from the app, it shows error 404. I've purchased this recently and am new to this. Any help is appreciated.

Dear, I can't purchase your app now, but I would. I just need to know of it supports:

Editing of alpha channel 
Layers with blending
Filters
