Vesa, Your idea is a good starting point. My opinion is, we should group some general symbols and use a more general name. For example, RCL would be Passive, All general semiconductors (Transistor, Diode, etc) should be put in Discrete and so on. I think creating to many categories can make the symbols difficult to find as Kicad do not define module to a symbol like some other cad, eagle for example. This directory structure should also be applied to module and 3D model directory too.
In addition, we should also define module naming scheme too. In my opinion, we should include model, pitch size and dimension (mil or SI) to all general components like R,C,L (for example, C2.5-5x12, CP5.0-13.0). One feature Kicad still lack is Pin/Gate swap and I'm learning the current schematic file structure and hope I can help with this. I will try to create a patch for this feature soon.
