it would be very handy with was possible to save a video into a board, as in "three dots > save to favorites" _ "three dots > save to boards".

Hey ​@Ana_Laura_Gomes 
Here’s a short video showing how to open a video in Boards.
Once the boards open you can choose which project you want to open the video inside. When you inside the project you just need to place the video inside the project.

Cheers

Nate
(I would have opened a board; however, I have other projects.)
