IDEA never ceases to amaze me...
I just added a subpackage in my source tree to an existing package; the new package's name was "ora-scripts". To my surprise, the folder icon of the new folder in the Project view did not have a little blue dot inside, and the context menu only allowed me to add Files and Directories (as opposed to Classes, Interfaces and Packages) to the newly created "package".
While this is indeed okay with me (as I was obviously intending non-Java files only to be placed in the new directory), I am a little worried because if I instead intended to use the directory as a part of my package hierarchy, I would not know how to "promote" the folder to a package.
Anybode here who does?
P.S.: Nevertheless, this amount of AI is something other IDEs can only dream of. Congratulations, JB!
