Inventory Overlay is an extremely lightweight client-side mod that shows your inventory contents right during gameplay. Just press the ` key (that's "ё" or "~" on many keyboards, but you can change the keybinding) — and all your items will pop up over the screen. No more interrupting to open your inventory manually. I designed it because I was so used to games where pressing TAB shows you allies or important info — and something felt missing in Minecraft. That's how Inventory Overlay was born: a simple way to see your gear and resources at a glance. Anywhere you go — in battles, building, or crafting — just one key press and you know what you've got with you. And yes, the opacity is customizable too: choose a transparency level so you can see through your inventory or tone it down a bit.
