Here are my scripts for your list #1
Description
Not sure if this will help, but I do keep a repo with some of my scripts on github as well:
https://github.com/IceDragon200/iek
It's a mixture of RMVX, RMVXA, RGSS2, and RGSS3; since I primarily worked in porting RMVX scripts to work in RGSS3 there are some crossover scripts as well
