Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Building an Array of "nop" write commands
adafruit/Adafruit_NeoPixel has assembly code for AVR. Plus ESP and Rpi which are a lot easier to read. And the protocol does look like inverted WS2812; it should be possible, although tedious, to modify the library to invert the pin.

What is causing a delay in my loop?
I looked at the neopixel github and I couldn't find any functions that took floats as arguments, so I think you can get away without using floats because they're reinterpreted as ints and truncated anyway, but if what you have works then don't bother.

RGB/RGBW mix and match help!
I'm not sure if that is the same thing. Back when I used it I got it from Adafruit which links to this Github.

NeoPixels on the Arduino Nano RP2040
The most important question first, the Adafruit NeoPixel Library does support the RP2040 since version 1.10.2. So make sure you are using the right version. To install the library please follow the steps explained here: Adafruit NeoPixel Installation.

Neopixels: ultra-low RAM
The Adafruit Neopixel library is great, but uses 3 bytes of RAM per pixel....in my application that's nearly 3kB (for the pixels alone!), which rules out the M328/Uno, and basically all of the 8-bit chips. I have a prototype running well using Adafruit's Neopixel library on a Mega 2560, but those are hard to source in the current market. And it's overkill for my use case.

Is it possible to program a 5mm neopixel LED in a way where one switch turns it on, and then the activation of another switch changes the color?
Using something like the Adafruit NeoPixel library there are commands to set intensity and to set color: setBrightness() setPixelColor()

00Key a 75% Keyboard
I only use keyboards running QMK or ZMK, so:
My Caps Lock key is a Control/Escape key (when tapped it behave like a Escape, when hold it's Control), and my left Control is a one shot layer switch key [1], which means I tap LCtrl once, and then press Caps Lock + 5 to get Ctrl+F5. Doable with single hand and more ergonomic as I have an unusually small hand.

Principles for Keyboard Layouts (2022)
I agree that reduced finger movement is a crucial step in achieving typing efficiency. This is nicely solved by mod tap modifiers in QMK/ZMK[1] where key acts as a char when tapped and as a layer while pressed.

Debugging a Failing Hotkey
If you have a keyboard that runs QMK firmware[0] with the VIA[1] feature enabled[2], then there is a convenient testing app available from the same place you customize your keys [3].

Just setting up my first corne layout. It will take a while for me to get used to this wow... It's taking so long to type. Attached is my layout, and I mainly use c# on visual studio. Any concerns/advice/suggestions are welcome. It will take a while for me to reply on this thing though.. haha..
I made a layout that I'm happy with. Spanish is my native language, so it has characters like the accents and 'ñ', but it's meant to be used for programming as well. Visual Studio uses a lot of Ctrl and Ctrl + Shift shortcuts, so I left them in the same place as the default Corne layout so I can press them both with my pinkie finger. Perhaps some of the ideas are useful to you.

Adafruit Feather RP2040 with USB Type A Host as a QMK converter board?
Also, it would be possible to do this for the RP2040. However, it needs some work to get working. but for example: https://github.com/qmk/qmk_firmware/pull/20999

If anyone knows of a good tutorial on how to make this tft display useful on a board controlled by an rp2040 and flashed with qmk configurator, I would be most grateful if you could point me in that direction. Gracias!
Ok, it's an ST7735, not too different from the ST7789. You should be able to get running by looking at their files in the QMK repo and going from there. You should also check their resources page.
