Question on Trello Powerup capability

Hi, I would like to port my Chrome extension for Trello to a powerup, but first I need to know if mutating the DOM to add, lets say, checkboxes to cards on a board to mark them as “selected” so I can then an operation on those is possible using powerups. If so, it would be great to know which should be the recommended way of doing it.

Thanks!

Right now there isn’t a way for Power-Ups to mutate the Trello DOM. It is something we know a lot of browser extensions use, but it isn’t something we’ve yet figured out how to add to our platform.

Unfortunately, we don’t really have a capability that lets you draw anything on the card front, but you could achieve a similar experience on the card back using the card-back-section capability: card-back-section
