I feel like the store on bedrock-edition was a mistake, and you shouldn't try to emulate it. I'd much rather just download a texture pack someone made online and install it without having to pay in-game money for it. If you made texture packs work more like they do on Java Edition I'd probably download this on release.
Exactly, unless the idea is changed, I might as well stick to the older version and hack it myself. It'll be a creator vs hacker thing for calculators.
EDIT: Also, I think the reason the Bedrock Edition store is so bad is because you aren't actually supporting creators directly, you're paying Microsoft in hopes that your favorite developers will be paid back. With the calculator, there is NO WAY to track this, meaning no chance of supporting the creator. At least if we make it free and forget the store, we won
t have to worry about payment.
The reason I hate the bedrock store is because they added micro-transactions to the game. You should just pay for the game and that's it. However, now they want you to get "mine-coins" and buy texture packs and "mods" instead of just downloading them on the internet and dragging them into a folder.
Before Microsoft owned Mojang there was actually an April fools joke about micro-transactions awhile ago. https://minecraft.gamepedia.com/Locked_chest
