I posted something about this around 6 months ago and a few people spoke up saying they would like it as well.
I run dual monitors, and it would be nice if Spark had the ability to dock against the edge of the screen.
If docking isn’t possible, another nice option would be for spark to remember it’s last position when you log in.
Every morning when I fire up spark it starts in the middle of monitor 1 and I have to drag it over to the left edge of monitor two.
If spark would remember it’s window position that would alleviate the nuisance of repositioning every morning.
