The software I'll install on my laptop once I ditch macOS for Linux

Interesting list, mixing libre software with closed freemium.

Thanks for putting a light on Oni :)

If you prefer KDE integration:

• Gparted has got a KDE fork, called KDE partition manager.
• Qbittorrent > Transmission,
• Kdenlive > DaVinci Resolve imo
• Konsole if you like single terminal with a nice looking translucent blur
  (i use terminator or Tmux to get split terminals though)
• Dolphin > Thunar on KDE w/ ffmpegthumbnails previews
• KDE widgets for note taking if you like have them hanging on desktop
• to edit image, try Krita it's very intuitive, lighter, nice looking and very powerful.

For mail, there's also Kontact which can does what thunderbird does and more (cal, contacts), in a KDE integrated style.
For screenshots Spectacle is integrated with KDE, it's got timing options. Although flameshot is great to edit on the fly, you can edit with a almost-light editor like Krita.

And if you're not into Firefox (waterfox being outdated), try
https://github.com/Eloston/ungoogled-chromium instead of Google Chromium (which is bloated with spyware).

Cheers

Great list, but didn't specify what each one is equivalent to on the Mac. For me, finding Typora.io was a revelation since it is the closest to Bear Notes that I've found so far.
