Re: With or without Harmony?
There is no reason you can't mix Harmony and custom code in the same project. Use Harmony when it helps and when it doesn't, stop using it. I recommend you find a Harmony example or demo that is closest to your end application and make it the basis for further development.
1) Put // CUSTOM CODE - DO NOT DELETE ... // END OF CUSTOM CODE around your additions to Harmony so that you don't accidentally delete something during code regeneration.
2) Always work under configuration management so that you can get back to good code in the case you do delete something by accident.
