Since a couple of people have been asking me about it, I'm going to post it here instead of sending everyone the links individually.
The original file is Mote/Kinematics's but I've spent the last month or so adding, removing and adjusting stuff in it.

With the help from several other top tier Summoners from different servers I have also managed to include a ton of nifty features.

I can't promise that I won't add or edit functions in the future, but for now I feel that this one is fairly complete.
If I change or update things other than gearsets I will update this post and add a changelog.

I've also kept the topic title for this thread fairly general, so if you have a personalized LUA you want to share, go for it!

Thank you Shirai 😁
