Hi there!
Just stumbled upon the issue, that the "clone" button in the gridder is not properly working if you use a stack with multiple objects in it, since the moment you hover down to the clone button it disappears and the one from the next object appears. Therefore there is no way to reach that first clone button.
Not a big issue at all, but I thought worth to mention.
T H A N K S for your good work! Lovit!
Best,
Marius
