Thanks a lot for sharing that plan !
I've been using FMPA14 and El Capitan for the past 2+ months - I was on the Public Beta program.
Aside from some issues with Fonts causing slow load times [not a OS X issue], I've had no problems at all.
I'm currently running the GM of El Capitan and several of those issues I can't replicate. No Windows open, or Windows open > 1 isn't causing crashes on my system.
Disclaimer: Of course, I not encouraging you upgrade to El Capitan just because I've had no issues.
