[One (M9) Android Development] Boostjunky:
There are only a few bugs that I have noticed with this ROM, and the only ones that stand out to me are all tied to the multi-user interface. I will list out what I have noticed as being "different" or "buggy" as compared to AOSP based ROMs I've used in the past with other devices.

Multi-User Bugs:

1) The settings shortcut in the statusbar doesn't work properly. Pressing it will open the most recent background app.

2) Making/Receiving phone calls doesn't work (and, yes, phone calls and SMS privileges have been granted to the new user from the main user account).

When a call comes in while on a multi-user account, the ringtone plays, but there's no way to answer the call. It actually does sort of the same thing the settings shortcut in the statusbar does. It opens the most recent background app, but what's even more strange is that while the phone is ringing, it won't let you get back to the launcher. It keeps you in the background app it opens up when the phone call comes in until the caller hangs up or goes to voicemail.

3) Push notifications don't get pushed through as consistently as I have experienced with AOSP based ROMs. If you're on the main user account, you could be getting several messages (such as facebook messenger or facebook notifications in general), and not know about them until you go to the multi user account and open the applications where notifications are waiting, and allow it to refresh , at which point you can become inundated with countless notifications from throughout the day.

The experiences I had with AOSP based ROMs were that the audible notifications would always come through to the main user account alerting you to the presence of a message or notification, upon which switching to the multi-user account would reveal what the message/notification was.

This rarely happens with this ROM (could be a bug with all Sense based ROMs that have multi-user support for the M9, but haven't been able to verify that). About the only time notifications seem to come through on the main user account is if you've just barely switched back over to the main account after allowing apps to refresh on the multi-user account. But, then again, after a while (presumably after the cache has been flushed or cycled through to other apps and pushed the multi-user apps out of memory), the notifications cease to come through to the main user account.

I doubt that many folks out there use multi-user accounts, but with my side business being primarily based on Facebook for communications and advertising, and necessitating a separation of personal accounts from business accounts, multi-user support becomes VERY important.

If I had known before buying the M9 that it didn't natively support multi-user accounts, I may not have bought it. In fact, I had no plans of rooting the device, unlocking it, or s-offing it when I bought it, but once I found it didn't natively support multi-user, it was straight to xda-developers for the fix.

I am very grateful for the addition of multi-user support, and despite some of its shortcomings in its current state, I couldn't manage without it.

If there is anything the developers can do to improve its functionality, it would be greatly appreciated.

Namely, phone calls as a first priority, and push notifications as a close second.

The settings shortcut malfunction can definitely be tolerated.

Again, devs, I certainly hope this doesn't come off as a lack of gratitude, or even as a complaint. I just wanted to bring some of these bugs to light since multi-user support is rarely mentioned, and I wouldn't be surprised if the devs weren't even aware of their existence.

Thanks to all of you for your hard work!
