[Galaxy Grand Prime General] Pbotelho:
1) Aww man I love using Trebuchet, I like to keep my install as small as possible so I'm not one for installing additional apps. I'm a resource junkie though, so its just a matter of personal preference.

2) Again, I'm not an expert, but I suspect it might be the device port. Previously, I've had an unofficial version of CM12.1 installed on a Galaxy Tab 3 as well as a CM12.1 based Pac-rom installed on a Galaxy S4. I'm not sure if this is something those developers corrected on their own or not when building their ROMs, so it could be the source. That's the best of my knowledge on the topic.

3) Will do for the brightness slider, but again, it isn't something I experienced on the other devices with CM12.1 and the sister project.

4) Yeah I played around with the governors and tried all of them. They all list 0MHz as the only option. Maybe its a CPU hotplug issue? I didn't try playing around with those so I'll have to get back to you on that one.

5) Look forward to the update :) I have a question regarding it though. I'm really familiar with updating custom ROMs through recovery using the zip file format, but this is the first time I'm using Odin to do the job. Will flashing an update with Odin this way cause a factory reset? Or will it update as expected?

6) A couple more graphical hiccups I remembered. The blackout also happens when going to About Phone>Status. In About Phone, the device field says unknown (doesn't bother me, I just don't know if its significant or not), the illumination for the hardware buttons isn't working (I usually keep them off to save battery anyways, but someone out there probably uses it). And finally, when switching recents by holding the home button, only the title bars of the individual apps are viewable. The content of the windows themselves is completely transparent so it looks like a series of floating title bars.

(Apologies if some of these features are already included, I didn't get the opportunity to check, I just think they're awesome)

Feature requests:

1) When phone is off and charging, percentage is displayed inside battery symbol.

2) CPU and GPU undervolting built into the kernel. These custom ROMs are much better than the stock ROM in terms of functionality, but the battery life on the stock Samsung experience is no joke.

3) If possible, more steps for CPU frequency adjustments, every 100MHz or so. I remember the stock ROM had limited options. My S4 is the example I'm going to use here, it has a step for every 108MHz.

4) USB fast charging, aka setting USB to "charge only".

5) Wakelock Blocker. Its built into the latest Resurrection Remix for the S4, not sure if that could be of viable use to you. It'll certainly help out with battery improvements.

6) Boot Manager. Decide which apps get to start at boot. Its built into Marshmallow and an xposed module also exists for this purpose, so really low priority on this one, for me at least.

7) This one is a doozy. Absolutely the one I care most about, but most likely asking for too much. USB tethering. Already exists, I know, but not the way I hope it to. I have an old WRT54G router with DD-WRT installed. My goal is basically this: Phone's network connection>USB Tether>Micro-USB-LAN adapter>WAN port of router. In this sense, the phone would be acting as the modem in a regular home network. I know its possible to do this if the router has a USB port, but mine doesn't, and I also know its possible if you have an intermediate device that bridges the connections for you. Like a laptop, PC, or raspberry pi. Cost efficiency as a student is what I'm working towards though, so this one is a wishlist request.

Ps. The only coding skills I have are from high school's Visual Basic and HTML, truly beginner stuff, and that was about 10 years ago. I'm running Ubuntu on a core i5-2500k with 16GB of RAM and about a terabyte of space though, so compiling is definitely a possibility with some instructions.
