Hello - bit of an odd request… is anyone aware of a way (more than likely a declare) to draw a line outside of a windows bounds. I’m basically after an interface element to draw a line of some sort between two windows. Doable? Thanks.
See posts about kiosk mode.
Grab the screen, display a borderless window the size of the screen, draw on your window?
Use an overlay… You could probably do it with declares and I think MBS plugin has it as well…

You Legends - thank you. MBS all the way 
What about a custom shape window for the line?
Windows OverlayMBS class you can make a window of any shape.
Please try it.
