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.

Code format question
In the previously linked version comparing colorCurrent.h == colorTarget.h or colorCurrent == colorTarget without the .h worked the same since the colors were fully saturated and at full brightness. Comparing colorCurrent == colorTarget compares the H,S, and V numbers all at the same time.

what the work of EVERY_N_MILLISECONDS_I ?
Use the first one for regular unchanging intervals. Use the second one when you need the interval to change over time. Here's one of Marmilicious' examples.
- Blinking stars
- stretching and then compressing a rainbow on a strip

Controlling WLED-ESP with another Arduino
Depending on the complexity of the animations you want, you could power them through the Arduino directly with a library like FastLED. https://github.com/marmilicious/FastLED_examples/blob/master/MIDI_test_v1.ino is an example.
- changing brightness of the individual led's?
- hopefully, last time asking for help...
- help again
- Addressing multiple individual Leds at once

More Coding Help Needed!
Take note in my example: https://github.com/marmilicious/FastLED_examples/blob/master/custom_pixel_array.ino

How do you make a code that does like 2 or 3 things simulatneously?
When you get a little more advanced it's not hard to extend the BWD code to hsndle any number of "time when something should happen". Or you can use something like the TaskScheduler library.

Understanding the rarely seen EVERY_N_MILLIS_I ?
Or just use TaskScheduler and never have to worry about this again. https://github.com/arkhipenko/TaskScheduler

Event-driven architecture
For reference, I'm a big fan of this scheduler in particular, due to it's simplicity, OO support and a neat extra of sleeping each unused millisecond (low power for free).
-
Current consumption between arduino and HAL?
One of my favourite low power techniques involves using a scheduller for your loop code, and sleep for 1 ms at a time when there are no tasks to run. As seen here.

Garden irrigation system based on ESP32
Have you looked at the task scheduler library? https://github.com/arkhipenko/TaskScheduler
What are some alternatives?
