Your real action bars as a guide anyone can hover: every button, its key and your reason for it. Made from one command in game and two files.
Unzip it into Interface/AddOns inside your game folder, e.g. World of Warcraft/_classic_beta_/.
In game, type /suite bars. It notes every button and takes a screenshot. Click Reload so WoW saves it.
WTF/Account/…/<Realm>/<Character>/SavedVariables/CharacterSuite.lua and the newest picture in Screenshots/.
Write a note for any button, then download one page to host anywhere: GitHub Pages, Neocities, a Discord upload.
CharacterSuite.lua, the screenshot, and if you have one, the .character.json you downloaded last time to keep your notes.
Everything happens in this tab. Your files are never uploaded.
