Now I'm using 7.0M1b and trying to use the latest EAP releases but almost all of them have some critical problems which prevent me from using them 100% of my time. From time to time new EAP releases of IDEA modify caches in a way that if I run older version after running a new one, it reports strange error messages unless I delete its caches. Would nice to have an option somewhere in the installer or elsewhere which allow me to specify place for settings or have a different default places for different builds of IDEA.
