1.) Force Closes too often.
It would help if you told us exactly what app is FC'ing; but in any case did you install per Dev instructions? Meaning, did you clear data+cache for the apps that are FC'ing?
2.) All FB contacts are synced even though I have "Sync only with existing contacts" selected.
Can't help you here, I don't use any social networking apps/sites. I've had the same email for 12 years, anyone that wants to get in contact with me, should be able to easily. And if they forgot, then I wasn't that important to them in the first place.
3.) No rotation on home screen when the keyboard is slid out.
I'll say it again, even though I've said it in another thread. This ROM and it's Launcher, are originally made for the N1/Desire phones. And since these phones do not have a slide out physical keyboard, the Launcher wasn't designed to rotate to Landscape under any circumstance, let alone sliding out a physical keyboard.
4.) Lock screen is messed up in landscape mode.
Read above; #3, same deal.
5.) Vibrate/Sound settings are incorrect.
Incorrect how? Mine are working perfectly. If you mean certain apps like Gmail and SMS do not vibrate even though you have your phone settings to vibrate "always"; then please look under each apps settings, you'll find a separate vibrate control setting for those apps; please set your sound and vibrate settings for those apps there.
6.) SMS are laggy showing up, and I can not receive MMS (handcent SMS)
--> I removed the stock messaging app...not sure if this would cause this or not.
Yes, that's exactly what you did wrong. Removing the stock MMS.apk from any ROM breaks that function, because all 3rd party SMS apps on the Android Market depend on the stock MMS.apk to send and receive MMS.
7.) Location doesn't work with GPS off.
This is highly known, and is already fixed in the next version of the Droid MIUI ROM based on MIUI v0.10.15.
