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.

Using external sram?
You can use one of the many SPI/QSPI PSRAM chips that are available. If you don't need to have it have it mapped as actual memory that you can malloc, using it should be pretty straightforward. I've written a library to help interface with SPI PSRAM over PIO & DMA, and I've tested it at up to 140MHz (with the RP2040 running at 280MHz): https://github.com/polpo/rp2040-psram

Best way to use ST7789 in ESPIDF?
ST7789 is a MIPI DCS chip so you can use HAGL with MIPI DCS HAL. There are a couple of examples and a video or two. Also sorry for blatant self promotion.

Unable to find fast lightweight TFT driver for TTGO T-Display and ESP-IDF
ST7789 is a standard MIPI DCS chip so you could HAGL with the MIPI DCS HAL. In addition to drawing rectangles etc I have used it four couple of proof of concept apps such as video player and old school demo effects.

LameUI - A UI Library for MCUs I have been making for past 6 months
Looks great! Don't worry about hours used or how many people will use it. Think of it as a learning experience. I did something similar with the only goal being to learn the C language.
What are some alternatives?
TFT_eSPI - Arduino and PlatformIO IDE compatible TFT library optimised for the Raspberry Pi Pico (RP2040), STM32, ESP8266 and ESP32 that supports different driver chips
lvgl - Embedded graphics library to create beautiful UIs for any MCU, MPU and display type.
picogus - Emulation of ISA sound cards on Raspberry Pi Pico (GUS, Adlib, MPU-401, Tandy, CMS)
LameUI - A very lame UI library for embedded systems.
Pico3D - Open World 3D Game Engine for the PicoSystem & RP2040 Microcontroller
microphone-library-for-pico - Capture audio from a microphone on your Raspberry Pi Pico or any RP2040 based board. 🎤
rpi - Microcontroller projects (RPi, Arduino, ATTiny85, ESP, Pico, STM8/32)
chafa - 📺🗿 Terminal graphics for the 21st century.
pico-debug - virtual debug pod for RP2040 "Raspberry Pi Pico" with no added hardware
esp-idf-st7789 - ST7789 Driver for esp-idf
hagl_esp_mipi - ESP32 MIPI DCS abstraction layer for the HAGL graphics library
LameUI_simulation - A crappy simulator for my even crappier UI library "LameUI"
