im also a one-person developer (mobile, utility) of an increasingly complex app. i totally get you on the having to load different subsystems into your brain thing. sometimes i will leave a separate, complex subsystem for the next day because i know my mind will be cleared of the current day's cruft, and ready to work optimally.
do you have a link to your project? i think one-person, deep projects are interesting.
