Replaced the folder with its own "alias" in the dock, as some kind soul advised.
More gripes: the fonts are too small, no way to set screen's DPI, or at least Finder's font and menu font (not that I can see, anyway). Safari still feels quite alien, may end up replacing it with FF.
Help window always on top, can't figure out how to disable that.
In general, things that I expect to be there are not, such as page up/down and other auxiliary keys, most configurations, other crap. No doubt I'll get into the groove eventually, but for now it's not pleasant.
