I have always been discovering new things about Linux distros while distro hopping. And when I get something I really like, I just copy the package name and make sure I install it in every distro I use in the future.
Let me start:
- Clipboard manager (Gpaste)
- KDE connect
I’d probably say the vast amount of packages that can be installed via the AUR, but since the rising popularity of Flatpak, we’re getting incredibly close to this.
My next want would be having the ability to make your system declarative (at least, the initial config) in a fashion that NixOS and Guix do.
