Also, because ~since I installed the rom I didn't give much feedback, well, there you are:
Almost no issues with it. "Pro tip": if you enable usb debugging when transferring files, the files ~retain their last modified date which can be very helpful. It may not retain the date created, but eh, it's ~something.
I had to made about 150gb.. using both a wired amd wireless connection (with total commander lan plug in). Lol, it took me about 2 days to set up the phone, so I'm probably gonna be careful not to soft brick the phone...
With magisk props I used both the "Mi 10 Pro" and "Mi 10 Eu" names ~without any issues.
(this thread proved to be helpful:

Now the issues:
1)Screenshots taken in (probably) lossy jpg isntead of png format. At least give the people the option to choose. I found an app that takes screenshots with the button combo (root access needed) and saves then in png. But after checking them with the eye on a pc and with an online pic comparer there seems to be ~no difference in the pixels between the png and jpg version, so the app probably just convers the pic to png instead of recording it in png from the fisrt place.
2)The issue
@lintern found.
3)It's kinda hard to toggle between personal and work profile. Yesterday there was an icon in quick settings that enabled this toggling, but today there isn't. (I think enabling work profiles emables the dual apps created). It may be that I changed the device name from "Mi 10 Pro" to "Mi 10 Eu" with magisk props module.
4)Cod mobile seems to be able to detect root access (if you leave it unhidden) and shuts down after ~30-120 seconds after booting the app. Though there is ~no message saying "root detected, disable it to play" and after checking the game tos it seems that they don't state that rooting is prohibited/bannable or something.
5)There's an app/tool with the initials LP which can do some modding on the phone (I think it can be used "illegally", even though the purpose of it is, I think, not illegall, so I'm ~not telling the name of the app). ~After giving it root access my phone was soft bricked and had to reinstall the rom. It's probably an android 11 issue (I think the app hasn't exactly adapted yet even if it get updated every ~2days). I fixed it by restricting root access to it. It may not work that well, but it ~doesn't brick my phone. Maybe I'll give it root access sometime when I'll have a good backup of my phone and enough time to set up the phome again if needed. (Pls tell me if you want me to remove the 5th point.)
Well, I think these ~are the things I wanted to point out so far.
Ps. Copying a pc .m3u playlist to the phone and changing the C:\Users etc. with storage/emulated etc., replacing the "\" with "/" and in short correcting the paths, you ~can easily import playlists (provided you put the songs on your phone as well).
Thank you people for the rom and the support!
Merry Christmas and a happy new year people!
