OCD renamer intelligently renames layers based on customisable settings. You can rename layers based on effects, children based on parents, parents based on children, mattes based on which type of matte they are and which layer is matted to them.
Selection based renaming & global (project wide) renaming
Rename using replace, suffix or prefix
Create custom aliases for effects and matte types. Eg rename Hue/Saturation as HSL, or Alpha Inverted to Alpha Inv.
Intelligently discards duplicate effect names
Vast naming flexibility via the preferences
OCD Renamer is compatible with AE CS6 and up.
