and it is vastly simpler than other options I have tried...
However there are 2 features that I would really, really like to see -
1) when you select an image to view, I wish it were possible to use an ellipse selection tool to crop, or copy and paste parts of the image.
There already is a rectangular selection tool, which is great, but sometimes I want an elliptical (circular) edit (if you can do this, maybe also add a free-selection tool too?)
2) I also wish it were possible to define a specific screen-capture size - in pixels. Sometimes I need to capture just a small part of my screen, and being able to define a specific size (128x128 to be specific) would simplify things greatly. I know it is possible to take a screenshot and then resize the canvas, however doing this for multiple files becomes quite tedious. This is an unusual feature that even many dedicated screen-capture programs are missing, and the ones that have it only support exporting the images to a small number of formats.
If these features could be implemented, I would have no further need for any other image editing/capture/display software and lots of "simple" editing or screencapture work that currently involves multiple steps and programs would become much easier.
