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.

How do I start out with displays?
Bodmer's TFT_eSPI is a graphics library for drawing to various displays, like the ILI9341, which is supported. It can be used with the Arduino IDE to program a Pico to interface with an ILI9341 using SPI, 8 bit parallel or 16 bit parallel interfaces.

Connecting ESP32 with TFT Display
For example, the electropeak link you posted showed a TFT LCD with the ILI9341 chip, and if you are using the TFT_eSPI library, this file needs to be configured https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setup.h , the default configuration looks correct in this case.

For this TFT Display, can I buy a breakout board online or would I need to make one myself?
I was under the impression that since this display uses a ST7789V, I'd be able to use the TFT_eSPI library which has support for this controller with ESP32 board. Is that a correct assumption on my part?

Any good/worthwhile Camera sensor modules for arduino/pico for still photography?
You could just buy ready-made ESP32 boards with an OV2640 camera built-in, then customize the example sketch from https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer to your liking.

ESP32 memory corruption
Are you perhaps this poster? https://github.com/espressif/arduino-esp32/issues/5250 - asking that poster for the list I just asked for went nowhere and it was auto-closed.

ESP32 S2 Help

The Nano ESP32
That has not been my experience at all as a user. ESPHome is even easier than Arduino and I haven’t touched firmware code in years.
The price makes a huge difference when you have dozens of them operating which is trivial with a decent hydroponics and smarthome setup. I also have a dozen boards just sitting idle ready to be called up to replace a failed one or use for a new project because they’re so cheap.
Not to mention the Arduino core is supported officially by ESP32: https://github.com/espressif/arduino-esp32
Who actually uses Arduino in production? Everyone just uses modules (for ESP32) or rolls their own using the Arduino board as a reference.

Arduino Uno R4 WiFi
They've done a good job of hiding the RTOS from you and making most sketches run fine without porting, but you're still running as a task under the RTOS, yielding between loop() calls[1]. This leads to mysterious timing issues if you aren't aware of it[2]
It doesn't appear that the Arduino core for the Renesas chip is using the RTOS, at least by default -- its main loop is literally doing while (1) { loop(); }, similar to how the AVR core works. [3, 4]
