^{Originally posted by MrTokyo12345 December 25, 2022} Hi, I love this plugin. and I would like to give other suggestions on how it could be improved even more.

• [X] When the crates menu is deactivated, you will not be able to /crates set menu
• [X] When the main menu is disabled, executing the /crates command does not show the Feature-Disabled message but does show the help message
• [ ] Addition of a new placeholders in the %keys% hologram this can be placed to let the player understand how many keys he has
• [ ] Possibility to customize the position of the glass in the crates Preview gui
• [ ] Ability to add some customizable buttons such as 'Close preview', 'Own 1 key click to open' for preview gui
• [ ] An Anti Lag system, if you try to open 300 keys with shift + right click it will only open 3/5 of them at a time. and not all 300 crates at once
• [ ] Cooldown to open a crates if you have already opened a crates you have to wait 3 seconds.
• [ ] Possibility to create VIP crates. only with permission will you be able to open that crates.
• [ ] Mine crates, while digging there may be a chance to spawn a crates in front of the player.
• [ ] A custom particle system
• [ ] New animations of opening crates

Thank you for your work behind this plugin 💖
