I read a lot and I think the new 1.7 is not going anywhere close to what many users express here.
Just a list of things people want:
1. Convert Black/White to mask. In PS its easy, take any black white image and use it as mask. Thats what an alpha channel looks like anyway. Not so in AFP. This should be a one click action.
2. Merge Layers. In AFP you need to convert layers first to pixel than merge.. that is annoying. We need an option to make that work in one step.
Although the content aware function is a great tool,you could do it with the inpaint function.
create a rectangle bigger as your image
put the rectangle to the back
select the image and the rectangle in layers panel
right click the layers>merge visible
hide the other layers in layers panel
menu>select>alpha range >select by partial or full transparency
