I’ve seen this requested from another user…
Being able to adjust image opacity is a feature I wish to see on Miro.
In product development, we might explore many concepts before refining our solutions. Being able to overlay a sketch, image, CAD screenshot, etc. with other images within Miro can be very helpful and will help my team collaborate more efficiently vs. going to other software/tools to accomplish this task and then re-uploading to Miro.
