One Billion Things is a mod which contains a ton of feature ideas suggested by
viewers of my channel and participants in the Discord Guild for my mods and
videos.
Most every feature which is implemented for these videos is included in one
mod, and each one can be toggled on and off using gamerules.
Check it out on GitHub Releases, Modrinth, or CurseForge.
I regularly pick suggestions both from the YouTube comments and (mostly) from suggestions from provided on the Discord. There are a number of factors that determine whether a feature makes it in, but I primarily seek out ideas that are simple in concept (though not necessarily execution), and which follow a rough theme for a video. Also, there are just a ton of ideas to sort through all the time. Basically, don't worry too much if your idea doesn't make it in, it might end up in a video later down the line, and I appreciate the suggestions either way.
This is actually explained in the first video, but the mod was originally going to be titled "One Billion Mods" as a play on the idea that I'd be making "One Billion Mods" in the course of this series. CurseForge really hated the idea of including "Mods" in the name of the project, so I came up with a goofy alternative.
