The nvidia driver comes under the non-free one. The nvidia 510 driver would be the most suited one for you. The latest might be for the 4080 or the 4090. Here is the link.
Mods please remove this.
There is a youtube channel LinuxScoop he shows many customisations try them if you like it.
Debian does ship nano not vim.
git not installed in ubuntu based distro was the shock for me.
Have you ever tried theming before ? Like changing gtk themes and cursor themes
Opensource is a more used term compared to foss. So popularity wise it was chosen is my guess.
Well don't know much about gnome since the first gnome I used was gnome 3.I never tried mate.
If I am correct mate doesn't have many touch gestures so there is no effect for it. If you want gestures gnome or kde would be suited. I maybe wrong if so any seniors do correct me 😉
In the GitHub it is written that you should only use fusuma.
About that error, in windows, you have two users say administrator and user. Both the users have their own user folder,they can't tamper with the others users folders right.
Similarly linux in default install has two users one the root and other the user. When you use sudo you are asking the root to open the file in its folder not in yours.
Kvaesitso has a setting to enable start right after opening the drawer if that's what you want though it's not as minimal like olauncher. https://www.f-droid.org/packages/de.mm20.launcher2.release/
