Hey bro, how's it going? I’ve updated the plugin with a few features that will help you get the result you're looking for.
1. I added a parameter to the plugin options that lets you hide the item description bar.
2. I also added options to change the icon background color, or even make them transparent using opacity control (just set the opacity to 0).
3. Simply disable the option to center the inventory on the screen and adjust the Case's X and Y positions using the controls located below the centering toggle.
4. Just adjust the X and Y cell spacing to create a gap between the inventory slots.
Please download the updated JS file, replace the old one in your project, and adjust these parameters accordingly!
Let me know if you have any questions.
