@Joshua William Davies - You were the first person who came to mind when I saw H5P, and then I saw it was your video that @Mishal was referencing.
Any tips, suggestions, thoughts?
Happy to answer! My way to just show the play button was slightly sneaky: I just made a series of grouped colored blocks the same color as the background and used them to cover the gray parts surrounding the play button :)
If you want to play with the templatefile in the video, it is also available in the Miroverse to download for free: https://miro.com/miroverse/a-miro-taxonomy/
Ah simply brilliant. Thank you for sharing! :)
