I have previously used Micrografx Picture Publisher and there is a feature that it had which I really miss. When using the rectangular selection, you could have freestyle type selection which Paint.Net has, or you could select fixed size selection or aspect ratio selection.
With fixed size selection, you would enter the height and width into textboxes in the toolbar (next to the selection type buttons) and left mouse button down would create a selection of the specified dimensions on the image.
With aspect ratio selection, you would enter the height and width in the same way and it would, on left button down, create (and resize on drag) a section using the height/width ratio specified.
A great reason for the ratio selection is I have an image that I want to resize to a screen resolution without stretching. By entering the height and width of the resolution and selecting aspect ratio selection, I can select as much of the image as possible to get an image that would fit the screen. So useful I almost want to install MPP again.
Cheers
