I thought we better move our conversation on "features that might come to be" to this community instead
At the moment I am working on customizing my own version the lesson on 'A for and against - essay'. Whenever one chooses to add a new activity one is limited to only one background/layout. Will it ever become a reality in this tool that one is allowed to change the background into an image? This would be a very nice feature to use in the cases when one wants to send students an activity with questions for discussion or just introductory information.
My guess is that you will never be able to let teachers add pictures randomly since there, of course, is the issue of copyrights to consider. However, maybe you could let teachers use a set of pictures approved by EF? Or something similar.
Just an idea
