Depending on your liking it can take a while to get it all set. Gnome has the appeal of being set in a way that is unique to Linux and being simple to get going and start working. KDE is a rabbit hole of adjusting and tweaking. But I appreciate that KDE lets me have fractional scaling and wallpaper slideshows without extensions that break with every major Gnome updates.
I can vouch for KDE doing it better, and in my opinion KDE does everything better except look unique like Gnome. KDE looks almost identical to Windows by default but it gives you the tools to be laid out however you want, if you want to put in the time.
Which errors are we talking about?
You have 1 notification concerning Nautilus, be it a file copy was completed or the like. If you click the notification center (the Date/Time on the top bar) and clear out your notifications there the 1 should go away.
While I’ve never had a problem in my 5 years of use, I only really used it as an automatic phone backup that my laptop could then pull the files in and work with. Not a lot of use, or devices. I don’t doubt that pCloud has their privacy issues, and I don’t doubt the horror stories. Like I said I’m not using my account anymore, and would love to try Nextcloud if I had the time to figure it out and the money to buy the hardware to do it with.
I also say that pCloud is possibly the best option. Simple install, free storage, and a cheap lifetime purchase for more storage. My only complaint is that they don’t support aarch64 yet, but I don’t need think there’s really anyone that does yet so I’m living with offline backups.
I run LineageOS on my phone so I sadly don’t have that feature. I found it was easier for me to quickly reply to texts but I would still fall back to typing with 2 thumbs (as I am now) and now that I have no swype-esque keyboard I think I may be faster without it.
My PC always has 3 games installed, and depending on the distro I’m currently on they may have come directly from the default repos:
I have lost count of how hours I have in all 3.
