Minecraft SMP Optimization & Futuristic UI

My survival-economy SMP is already running a healthy mix of role-play story lines, custom items, and plenty of NPCs, but performance and polish are starting to show their limits. I want a seasoned Minecraft plugin developer to jump in, give the entire backend a health check, and deliver a slick, futuristic-style UI menu similar to what you see on CubeCraft.

Here is what I’m aiming for:
• A complete once-over of the server’s configuration (plugins, permissions, databases, timings) to spot bottlenecks and squeeze out extra TPS.
• A new, fully functional main menu built in the CubeCraft vein—clean animations, neon accents, and an intuitive flow that ties together shops, quests, and player stats.
• Guidance—or if possible, direct implementation—for adding custom armour, weapons, and other ItemsAdder assets so they slot seamlessly into existing gameplay.
• Quick recommendations on my custom mobs, skill trees, and achievement setup; they’re mostly in place, but I’d love your feedback on best practices and performance.

Acceptance criteria
1. Server maintains stable performance under stress testing with the new menu and ItemsAdder content enabled.
2. UI menu matches the agreed futuristic mock-up, is responsive, and opens without noticeable lag.
3. All new armour/items register properly through ItemsAdder and appear in game without texture issues.
4. A concise hand-off document summarises changes, optimisation steps taken, and any future maintenance tips.

I’ll provide full access to the test environment, current plugin list, and source files for existing menus. Looking forward to seeing the server run smoother—and look sharper—than ever.
