How much depth can you really get?
It's a screen capture program. How much usage of a screen capture program does someone really need to go through to constitute having "truly" used it?
Incidentally, in the age of phone apps that are about the price of a coffee, doesn't $20, much less $50, seem like a little much for a feature-replacement program of a function that already exists (in a substantially more limited form) in Windows to begin with?
