I believe the working directory could be the only place the user needs to care about. Currently the user has to access the installation directory to paste new themes and Ladspa effects.

Proposal: Ladspa effects, themes, VST effects, SoundFonts and GIG files? get a folder in user directory, just like the user presets have. The path in settings would default to this folder, the user can still change the path of course. Templates get a folder in the project folder?
