How to make a tier list
Name your list, then add what you want to rank: type items one per line, or add pictures with the button, by dragging files onto the board or by pasting a copied image. Pictures are shrunk to 320 pixels on their longest side so the board stays quick.
Ranking. Drag items from Unranked onto a tier; on a phone, press and hold for a moment first. Or click an item to select it and use the bar below the board: send it to any tier, nudge it left or right, rename it or remove it. With a keyboard, Tab to an item and press Enter; the arrow keys then move it within its row and between tiers, 1 to 9 send it to that tier, 0 back to Unranked.
Tiers. The settings button on a tier label renames it, recolours it, moves it up or down, empties it or deletes it. The label text switches between dark and white so it stays readable on any colour.
Saving and export. The board saves itself in this browser: text in local storage, pictures in IndexedDB. Download PNG draws the ranked tiers, not Unranked, 1,200 pixels wide.
