single-file-compilation of classes from other project

Hello Sebastian,

I think this was never designed a feature; the fact that it was possible
was an accident. There is no configuration for this.

recently a customer upgraded from Idea 3 to 10 (yes, he did).
Everything went surprisingly smooth considering the big version jump,
however one "feature" appears to be missing:

In Idea 3 it was possible to open java source files from other
projects (via ctrl-b for instance) and compile them in the current
project, without compilation of the actual project, the source file
belonged to.

Ist this a feature lost in the tides of time or is there a
configuration for that behaviour?
