Orderly

Orderly brings structure to frame organization in Figma. It has two tools: Rename, for batch-renaming frames with numeric, alphabetic, Roman numeral, or alphanumeric styles (plus prefixes, suffixes, and directional sorting); and Number, which overlays position indicators on frames with full control over placement, font, color, and size. Reorder frames by drag-and-drop or auto-sort by canvas position, with a live preview as you go.A couple of even tighter options depending on where you're using this (App Store listing vs. README vs. tagline):

Shorter still:

Orderly batch-renames and numbers your Figma frames — numeric, alphabetic, or Roman styles, custom prefixes/suffixes, 9-point placement, and live preview as you configure.

One-liner:

Batch rename and number your Figma frames, with full styling control and live preview.
