I've just moved away from using ColorSnapper2, and I think this app should implement some of the extra features that ColorSnapper2 provides for its color picker, as they improve the user experience significantly.

Features

1. Being able to resize the loupe with the scroll wheel. This is pretty useful as the current size of the loupe feels very small to me, it feels a bit disorienting, as if I can't see enough of the surrounding to orientate myself easily, I'd like to make it bigger.
2. Current color tooltip. I like this a lot because it allows the color picker to be used for more things, for example I can check if something is pure black or if two things are of the same color super quickly, currently doing the same with this app involves opening the window, which just breaks the workflow for me.
3. Close-up mode. When pressing ctrl on ColorSnapper2 the loupe sort of zooms in into the screen, showing a bigger loupe, much bigger pixels, a pixels grid and importantly also the loupe moves more slowly. Those are pretty useful features IMO as picking a precise pixel currently with the app is not a smooth as it should be, it's just too easy to move the cursor accidentally to a neighbor pixel and I find that I physically get closer to the screen just to have a better view of the pixels.
