Currently we can set links to any specific artboard. This is very helpful. I use it for creating a button on every slide that will take me to a contents artboard, where I can link to different flows.
The problem in this setup is that, when in prototype mode, there are a lot of links drawn between the artboards, as each artboard is linked to the contents artboard (see attchment).
I find this can be easily alleviated if I could link the buttons to the 'home artboard', and so it could spare having to draw the links to that artboard.
So I propose adding 'Home Artboard' as a target option: And elements linked to the Home Artboard will not draw their link-arrows in prototype mode.
