This is beautiful, stable and configuarable enough to waste a large chunk of your working day.
On paper, it sounds like more of that shoddy, unoriginal, disk space wasting, high-school-project freeware that we've all learned to avoid. But this is so much more than that. With a little imagination and some serious programming, StickSoftware have (yet again) recycled an old idea and created something new and completely in a league of its own.
Unusually, there aren't any nag screens or disabled features in unregistered copies (which, alone, is surely reason enough to register) but, if you like it and can afford to make some sort of donation, please don't forget to pay - I want to see more from StickSoftware, don't you?
