It's the little things (itlt) is a modpack branding tool: it changes the game window title and icon (with HiDPI, ICO, ICNS and PNG support), can show a welcome screen on first launch and warns players about too little RAM or the wrong Java version.
It can also pre-install entries in the Multiplayer server list without wiping players' own servers. Works with Forge and Fabric on Minecraft 1.7.2 - 1.21.5.
