I retrieved and installed the 123.168 EAP release and when I launched it, it asked me if I wanted to import my old settings or start from scratch. I thought something might have gone wrong, so I "force quit" it (on Mac OS X) and relaunched. The second time it didn't ask me, but was a vanilla installation (but without walking me through the usual first-time set-up wizard).
I quit then and relaunched 123.165 and all was as before.
Is this intended? If I want continuity do I import my previous settings? If so, will I get 100% carry-over? (I tend to need to spend a lot of time getting things as big and complicated as IDEA just the way I want them and having them revert is something I avoid as much as possible.)
