Frame around video layer in layer

It would look nice to be able to put a border or frame around the edge of a layer when it is inside another layer. For example when it is our face in a smaller layer explaining what’s happening in the full-sized layer. Uploading a screenshot of what a colleague did using Ecamm which is only for mac.

His face was a video talking it through the images.
Thanks.

Yes this will be lovely. I do this with some other softwares, please let’s have this on manycam as well.
I have also requested that you create options for users to create their own custom transition. I love move transitions which I do with my other softwares. It would be lovely to do this on manycam. This will place it way above many softwares there
