Something too complex; I fear I won't ever have enough time to try it and figure out how to apply it for it to be of any use for me.

I wish there was a simpler and quicker introduction into the tool's capabilities than an hour long video and a text article saying it's a swiss army knife that does a lot of things. I need 1 or a few glimpses into it, there's no need to cover every capability thoroughly, show just enough to have some general understanding of how it works and how to use it and how to solve some common problems with it.
