If you got it through steam: ...\SteamLibrary\SteamApps\common\RPG Maker MV\dlc\KadokawaPlugins
If you got it through the website: there's a link in the email you received that gives you the DLC content.
Anyway, press F10 in the editor, add a new Plugin, there should be the "TitleCommandPosition" plugin in the selection by default.
In the parameters section, you can change the width of the title menu, and its position. (offset x needs to be negative to move the window to the left, etc)
As for skipping the title menu to create your intro before it, there should be a way (plugin) to skip Scene_title... something that overrides this (rpg_scenes.js):
Code:
Scene_Boot.prototype.start = function() { Scene_Base.prototype.start.call(this); SoundManager.preloadImportantSounds(); if (DataManager.isBattleTest()) { DataManager.setupBattleTest(); SceneManager.goto(Scene_Battle); } else if (DataManager.isEventTest()) { DataManager.setupEventTest(); SceneManager.goto(Scene_Map); } else { this.checkPlayerLocation(); DataManager.setupNewGame(); SceneManager.goto(Scene_Title); <--- this takes you to the title screen Window_TitleCommand.initCommandPosition(); <--- this positions the title screen menu } this.updateDocumentTitle();};
