[ONE Q&A, Help & Troubleshooting] neverone:
Hey guys!

I need some help and a bit of advice concerning my OPO. This is probably a set of questions for people who are more into rooting and modifying roms in general.

I recently updated my OPO to COS13 (no thanks to OTA, I had to install the Cyanogen uppdate checker from Google Play, and then manually flash it from recovery). Since i flashed it over my existing COS, with all the data left intact (not, recommended, I know), some small bugs appeared and I still encounter some issues I had in the COS12, so now, more than ever, I am determined to root it, and put latest CM13 snapshot.

I'm not new to rooting, and I think it's a pretty straightforward procedure concerning OPO, however, I learned that after flashing new CM rom, I have to also flash Gapps. And here lies the problem, since there are so many Gapps packages on Open GApps Project that i don't know which to choose. I was maybe thinking going for the bigger packages, since I use quite a lot of Google Apps and wouldn't mind them on my phone preinstalled.

Then I learned that in those larger GApps packages there are some Google apps (full, stock and super) that overwrite existing apps in the ROM (like messaging apps, calendar etc.), which is more or less fine by me, but my biggest dillema is Camera app. I've read about Cyanogen introducing its Snap camera app that is supposed to be really good, but some people say that Google Camera app is also good, and if I choose stock GApps package, it will overwrite CM's camera app. Can somebody tell me frome experience what would be the better camera app for my OPO? Clearly, the difference is in software, and which software creates better, and clearer image.

The other questions I have are connected to Aroma GApps installer. This sounds great as it allows me to pick by hand which apps I do and I do not want on my phone. It also (allegedly) allows me to install a Google app along with the dedicated app from the CM's rom. In this case I could have both Google's camera app on my phone and CM's camera, and I could test them myself.

My questions concerning Aroma Installer are:

1. Is is really true that I can have two dedicated apps one next to each other, working on my phone without errors?

2. If the answer to #1 is Yes, once I tested them all, can I remove the unwanted one from system/app folder without any effect to my system, or do I have to reflash the rom, and reinstall GApps via Aroma all over again?

3. On the Open Gapps site, under Aroma installer, it says that the only TWRP recovery version known to support Aroma installer on OPO (bacon) is 2.8.4.0, while somebody somethere told me that I should flash TWRP 3.x.x.x before flashing CM13. Where lies the truth here? Can I flash CM13 snapshot from TWRP 2.8.4.0, then install GApps via Aroma, and then update TWRP?

4. If I flash any GApp, and after a while want to switch back to stock CM's app (for example messaging or calendar app), is it possible to simply extract the corresponding app from the rom's image, copy it to system/app (and of course, changing app permissions), while in the same time deleting the appropriate Gapp from the app list, or do I have to make a clean flash of the rom and to flash GApps from the beginning?

I probably have more questions about the whole procedure, but for now, this is what I can come up with.

Thanks in advance to anybody who was willing enough to read my essay and answer me. :)
