Everyone mentions the learning curve... I just learned it myself and pretty much was up and running after an amazing and fast paced intro tutorial of about 20 mins. Maybe it used to be hard to learn because now it seems to me very logical. Just dont bother without watching a video first.
I wish more people would use it so more footprints would be available, although making them from a datasheet is trivial. And fun...
I dont wish bad luck on the good folk who make eagle but long live free software.
It is hard to learn when you come from Eagle or expect it to behave like "normal" Windows drawing application. But that holds for mostly any EDA package or even general purpose CADs.
Biggest problem with KiCad's UI is that while it's UI is actually highly consistent when it comes to drawing itself, it's GUI is a mess (things that are only on toolbar or only in main menu, no correlation between icons in menu and on toolbars, crucial functions buried in random non-related dialog boxes, behavior and feature set changing depending on graphics backend etc.).
But in comparison with various other EDA packages (including Eagle) I find the overall experience mostly consistent and logical. In comparison with one very expensive EDA package at least snap to grid works in a way that is actually usable and all KiCad windows use same GUI toolkit.
