Ferdium - Allows to run multiple online chat/mail accounts in a single interface, without cluttering our browser. It's an electron-based software that takes a lot of ram, but it's a nice way to organize stuff and avoid getting overwhelmed.

OliveTin, gives you a clean web UI for pre-defined shell scripts, with a dynamically reloadable YAML configuration.

There are a ton of things you could use it for, but I use it for container and system updates. A pre-processor runs on a schedule and collects a list of all containers and systems on my network that have available updates, and generates the OliveTin YAML config with a button for each. Loading up the OliveTin webUI in a browser and clicking the corresponding button installs the update and cycles the container or reboots the host as needed. It makes it trivially easy to see which systems need updating at a glance, and to apply those updates from any machine on my network with a web browser, including my phone or tablet.

sgt-puzzles. Simon Tatham's Portable Puzzle collection.

Contains a bunch of simple puzzles, of the minesweeper and sudoku style. Loopy is my favorite.

Available for Linux, Windows, MacOS, Android, and anything with a web browser and a mouse. Packaged in Debian and F-droid, and probably many other places.

I like it for time wasting in lines at the DMV, for a low-stakes game when anxious, and for falling asleep.
