I know absolutely nothing about how scripting but I had a feeling it'd be a from the ground up situation. As for the reasoning for such a script like dpclothing is because unlike most, if not all, trainers require you to go through a bunch of items thus breaking emersion unlike the rotary menu where it has two options, on or off.

For those who haven't heard of DP Clothing, it is a script on fivem that allows you to toggle neck props, hats, vests, shirt and pants, shoes, bags, and more. The unfortunate thing about it is that as far as I know there isn't a script like it for single player, let alone one with a menu that pops up if you hold a certain key. Image of what I mean.

In case you haven't heard of brownout https://en.wikipedia.org/wiki/Brownout_(aeronautics) this is something that would be nice to see when landing on the strip in grapeseed or when landing on the beach
