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.

Actually Portable Vim (With a Cute Vimrc)
I don't know what you mean by color management - is it the calibration of the display with xrite/argyll?
For ICC profiles colormgr can help: https://wiki.archlinux.org/title/ICC_profiles#Wayland
If you just need basic brightness, contrast and gamma, wl-gammactl should do that: https://github.com/mischw/wl-gammactl
BTW Hyprland is not required, it's just the most practical way to have shortcuts key mappings in Wayland

Setting Contrast Value in Wayland
However, this does not work in Wayland since it obviously belongs to the X Window System. I started searching the web for a possible solution and found wl-gammactl, which is a GUI for wlroots (https://github.com/mischw/wl-gammactl) and the gnome-gamma-tool (https://github.com/zb3/gnome-gamma-tool), but neither of them seemed to work because of missing dependencies, which can't be installed or invalid version numbers of required packages (e.g. found 1.20 but need: '>=1.23'). When attempting to build the gnome-gamma-tool, the following error message appears (despite Colord being installed):

Being productive in Plasma 5.23.2 - So I've heard KDE Plasma is bad with Wayland and multi-monitors...
It's very much possible with Wayland. Whether Plasma supports it is another question, unfortunately. Great program though, you can control it with commands and set an invert screen colors keybind.

How to invert screen colors?
What would be the best way to implement this? I tried wl-gammactl https://github.com/mischw/wl-gammactl with those settings but the screen just goes fully white?

Import gamma colors from X11 to Wayland
Probably it just support sway as said here on github

How to control OLED brightness in Wayland
Wayland is the protocol applications use to talk to compositors. What you need to control (this kind of-, since I assume you want a software overlay) brightness depends on the compositor/desktop environment you use. For wlroots based compositors (wayfire, sway) wl-gammactl or wlr-brightness could be useful. For Gnome (below version 40) the soft-brightness extension looks like what you need.

What are some alternatives?
swaybg - Wallpaper tool for Wayland compositors
wlroots - A modular Wayland compositor library
kiwmi - A fully programmable Wayland Compositor
swaylock - Screen locker for Wayland
wdisplays - GUI display configurator for wlroots compositors
xcalib - Load 'vcgt'-tag of ICC profiles to X-server and MS-Windows. Works on calibration stage, which can be a precondition for display ICC color conversions.
gnome-gamma-tool - A command-line tool that lets you change gamma in GNOME and Cinnamon (with Wayland). You can also adjust contrast and brightness. It works by creating a color profile with the VCGT table, so that changes are persistent and don't interfere with other settings like night light.
swayidle - Idle management daemon for Wayland
wdisplays - Mirror of cyclopsian/wdisplays
