Image Processing

SLK_img2pixel

Helps you turn your textures into pixelated ones. The result images usually dont really look like a just pixelated version of the original, instead they look like pixelart.
Examples: Also most of the backgrounds are pixelated using this tool.
Cool tip:

• Load an image you like the palette of
  
• Generate a palette (Restricting the Color count is a good idea too)
  
• Load another image you want to pixelate (do not regenerate the palette)
  
• Now you can use the other images palette for pixealting!
  

Pixel Composer

A node-based tool that helps you create pixel art/animations. It has an insane amount of features, and the ui feels great.
You can use it to process(even batch process) iamges, create 2d or 3d animations from already existing assets.
It has a CLI tool aswell so you can use it in your pipeline. Here's how I made the glitchy version of the particles you can see on the Modeling page. It generates gifs for all the gradients you can see on the left using %i to name all of them.
In the end I only ended up using the red one, since I can just hue-rotate it to my liking:

Notes

Obsidian

A really cool note taking app that uses markdown. It has a lot of features like linking notes, tags, and has lots of plugins, and my favorite feature is being able to easily customize it. My current theme is up on GitHub.
I also love that there's an Excalidraw plugin, and you can embed the drawings in your notes. There's also plugins for Kanban boards, which I use for my projects.

Excalidraw

I know I just mentioned Excalidraw under Obsidian, but it needs its own section. I use excalidraw for teaching, for explaining myself and as a whiteboard for figuring thigns out. Its simple yet powerful, and you can always just launch it in your browser if you need it fast. I've also used it in uni for explaining things to my friends, before big exams lol.
