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.
