NeoBuyerLite 1.5 update Brought a lot of new things to the plugin:
1 - Added a button to the menu - "Hand in everything"
This button hands over to the buyer absolutely all the items he accepts in one click
2 - Support for custom Minecraft heads
The plugin now fully supports custom Base64 heads
3 - Added sounds
Namely, the sound when successfully and unsuccessfully handing over items to the buyer
4 - Added the ability to execute a command when clicked
As an example, I added display of information about pumping up a buyer when you click on the corresponding item in the menu
5 - Added the ability to hand over all items not only using the middle mouse button, but also using Shift + Left mouse button
for versions 1.20+ and for podzhavlauncher
because there is no middle mouse button
