I should word it better; It's easy to get into, but hard to master.

For example, in the video I put, it's simpler than it can be; the person lets the program do all the work with "automatic curve correction", which does a good job of fixing the curves (most people wouldn't be able to notice), but it could be a lot better if manually corrected afterward (takes lots of effort).

As for Saku's, I think it's just background removal; while you can cut out the background manually and turn it into transparency, there's other things like feathering and masking that makes it even more accurate, and even going as far as manually filling in damaged portions that wouldn't be able to be cut out otherwise by using what you already have about the image ("information")
