/hub (or /smply menu) is the menu players learn first.

server_name from config.yml. Hearts, sell, shop, auction, bounties, and quests hide when their modules are off.
What sits on the hub
Typical tiles after Lifesteal or Economy:- Profile and personal settings (TPA, HUD)
- Kits, rewards, quests, leaderboards
- Travel: spawn, homes, warps, RTP, TPA
- Market: sell, shop, auction
- Hearts and bounties when those modules are on
- Rules and help
/help is a 27-slot command list. /rules is a 27-slot rules desk. /profile is stats plus toggles.
Catalog chrome (54-slot desks)
Auction, shop items, kit overflow, bounties, quests, and leaderboard pages share the same controls:
Search matches material name, listing id, quest display/id, or bounty target name.
27-slot pickers
Shop categories, the kit picker, and leaderboard categories stay small: content on the middle row, Back at slot 22. They do not get search chrome.
/homes, /warps, /rtp, /tpa) row-center their content. Incoming TPA can open an accept/deny menu for the target.
Style
gui.yml style picks mint, slate, lifesteal, or economy. Lifesteal and Economy presets set this once. Change it in Server Settings (Display page) or YAML, then /smply reload.
Search capture is chat, anvil, or sign (gui.yml input.search). Bedrock players use input.bedrock (default sign). Type cancel or leave empty to abort.
Layout lives in menus.yml. See Configuration for slot maps.
