Mass Editing - Aedif/multi-token-edit GitHub Wiki
Mass Edit allows you to edit multiple placeables at the same time.
Select placeables and engage multi-editing using Shift+E
keybinding.
Common data shared between all placeables will be highlighted as ${\textsf{\color{green}green}}$, differing data as ${\textsf{\color{orange}orange}}$, and flags as ${\textsf{\color{purple}purple}}$. The newly added checkboxes to the right indicate which fields will be saved on Apply.
In addition to this keybinding Token and Tile HUDs will contain a new button if multiple tokens or tiles are selected which will also open up this modified configuration window.
