They've fixed surprisingly many of the quirks, but my biggest gripe with Snap is that they don't like to add documentation with new features. A lot of the older content has a nice "help..." context menu option with a description of what it does (which is often out of date itself, e.g. the "split" and "join" by blocks feature isn't shown on those blocks), and newer blocks have the context menu option... but nothing pops up.
