LoneDev if you could just make it work with geyser, that would be a lifesaver. As someone who is starting up a crossplay server who loves your plugin, I know personally there are many servers like mine that would greatly appreciate a more streamlined way to make sure bedrock players don't see things like dyed leather when it's supposed to be some awesome custom armor, or like some of the blocks that come with itemsadder, for free, they are invisible blocks to bedrockers. It really ruins the atmosphere and overall enjoyment for players and limits the ability to do things like sell crates with custom armor because to the bedrockers, it's just lame. They don't feel like they are getting what they paid for, and really they aren't. :/
If you decided to do this, and make it as an upgrade or something we had to pay for I would be open to that even. like as an addon? or a separate plugin. Whatever is easiest for you!
