EvoRoy
I had the same question, at first i was adviced to not check anything until i got more comfortable with knowing what those things are. I would recommend to do the same, dont check anything. Although i did go back and reinstalled it with see thru notification bar, and i also checked the battery hack for the Evo gives better battery life, but thats it...oh! I did also check the Launcher Pro theme becaue it more cusotmizable that way (if you are familiar with LP) its pretty cool but in order to get that you have to go to settings applications then find HTC Sense and reset defaults, then press the home button and you will get Launcher Pro option. Hope this helps, and by the way i keep switching back and forth from Cynogen and MYN, they are both great ROMS!
