I tried this yesterday, and the first thing I discovered is that the background is covered up by all the tiles anyway. If this had a way to make the tiles semi transparent, it would be really nice, and I would probably buy it. But one thing it does that is really nice though, is let you set the number of tiles in each column, up to seven (maybe this is based on the resolution of the monitor). So overall, I don’t know if it’s really worth paying for after the trial runs out.
