Jádro & launch

Brainstorming

💡 Import from other launchers — Detect + import instances from Prism / CurseForge App / MultiMC / Modrinth App. Killer for switchers.
💡 Clone instance — Duplicate an instance in one click (test mods/versions without breaking the original).
💡 Mod update checker — Per-instance 'X mods have updates' → update in one click (incl. 'update all').
💡 Auto-snapshot before update — Automatic instance backup before a modpack/mod update (tied to delta snapshot/rollback).
💡 Modpack update changelog — On modpack update, show what changed (added/removed/updated mods).
💡 Skin library + changer — Skin library + apply directly from the launcher (we already render skins).
💡 Resource pack & shader manager — Same experience as the mod manager, but for packs and shaders (browse/install/enable per instance).
💡 Java 'Optimize' — Auto-tune JVM args + RAM per machine and pack (Aikar-style, automatic).
💡 Quick servers from modpack — Modpacks often offer an official server → one-click add to Server Hub.
💡 Discord Rich Presence — Show what and where you're playing (opt-in).
💡 Offline / airplane mode — Full launch from cache without network (even without MS re-login while the token is valid).
💡 Playtime stats — Hours per instance, streak, 'most played', chart.
💡 Export / share instance — Pack a configured instance and send it to a friend (reproducibly, see lockfile).
💡 Compatible mods only — When searching mods inside an instance, filter to that instance's loader+version only (no dead ends).
💡 Custom instance icon — Upload/pick an icon instead of the modpack logo or letter.
💡 Quick Play / direct join — MC 1.20+ quickPlay: launch straight into a world/server, no menu. Builds on Server Hub → one click from the command palette = in-game on a server.
💡 Pre/post-launch hooks + wrapper + env — Per-instance: custom pre/post-launch script, Linux gamemode/mangohud wrapper, custom env vars.
💡 Running instances — management — 'running' badge, Kill button, multi-launch, minimize-to-tray while playing.
💡 Modpack version switch — Update/downgrade a pack to a specific pinned version + rollback.
💡 Datapack manager — Same experience as the mod/resourcepack/shader manager, but for datapacks (per instance/world).
💡 Browse filters — Category / MC version / loader / sort in the unified CF+Modrinth catalog.
💡 Log upload / share — One-click log sharing (mclo.gs or a custom paste). Pairs with the crash parser.
💡 3rd-party auth (authlib-injector / Ely.by) — Alternative auth server + skins for offline accounts. Weigh against the STYGION ID direction.
