Settings and activity

Yes scroll, should be available as a transition trigger.
I suppose the most appropriate implementation would be to be able to attach the trigger to an element/symbol y position (for example when it enters or leaves the viewport)
Please note that the scroll direction should also be considered.

I'm sorry to say that the way the global style variables are implemented in xd leaves a lot to be desired...

The existential purpose of Global Style variable is to allow global editing.
if a new character style needs to be created for each possible color of that character style it defeats the purpose and even more so considering that colors can be saved as global style variables in their own.

This would also tremendously improve the new shared project's grid view.

for some reason re-ordering layers (via drag&drop) into the layer panel is not possible for children of:
. a mask group
. a repeat grid

All the arrange commands and shortcuts (bring to front, send backward, ...) do work as a workaround.

Yet I find it way more intuitive, easier and faster to manipulate the object in the layer panel directly.

as a workaround the arrange commands and shortcuts do work.
