Unsure how well known it is, but flameshot (screenshot tool).

I prefer CLI usually, so: zoxide, the zsh git plugin for aliases (e.g.: gst is git status), fzf zsh plugin and the tldr command comes in handy sometimes.

Also, this might be useful just for me, but due to orientation of my living space, I have to fiddle with monitor brightness at least three times a day so I made myself a little Qt tray wrapper around ddcutil’s ddcquery which can change standard vesa monitors brightness/contrast (DDC/CI communication).
There is also ddcui/gddccontrol GUI that does the same thing.

For cli oriented folks, ncdu is a great cli alternative of QDirStat

Friend just hopped to Bazzite from Windows.
I was hoping the atomocity would be a great boon - you kind of can’t break it right.

Well, he wanted to configure RGB lighting on his mouse but the flatpak openrgb did not work, supposedly the udev rules included in bazzite by default, are not up to date or there was some other problem.
As such we had to install openrgb the usual system-wide way, with rpm-ostree in terminal - something I was hoping he would never had to do.

Yeah Nick (the guy behind this) is one of a kind (in a good way) lol

Also recommend checking out this demo of NotCurses https://www.youtube.com/watch?v=cYhZ7myXyyg it’s great

Lot of indies and linux compatibility is high in my priorities.

As a (semi) power user I also use btrfs subvolumes to create “partitions” (single disk system, @root, @home, @docker), allows for making snapshots only for system or user data, etc.

All around, I love btrfs and I am never going back to journaling fs like ext4
