So this have been troubling me for years, but 'til I asked Wordzilla about it, I didn't found a possible solution, which would be GridMove. OK, so the problem is that I want to fit in the exact center of my desktop a window of any given size. Yep, no resizing (at least for now). A shot to explain the problem.
Feature request for GridMove
See that "Fusion 3.51 - blablabla" window there? I want to move that window (960x720, but should be extensible to any window size) to the exact center of my desktop (1280x1024, but it should be extensible to any other resolution). Essentially, it's a math job that sometimes I did using a ruler (no kidding), but with some other windows it was a nuisance. If all windows could be maximized without side effects, there would be no problem, but giving some of the software I handle, that's no possible, either because the software was designed to have the window like that, either because it looks terrible on full screen (this is the case, for example).
Well, I think that's all. I hope I expressed my problem/request clearly so you could understand what I'm asking. Feel free to flame me if the written expression of my thoughts is terrible, the request is unrealizable, if I'm a tiny little perfectionist.. well, you see the point
