Hi Pierre! Thanks for your nice words!
To take your last question first: In the current alpha version it is not possible to add clones to multiple drawings in one go. But this functionality is on our todolist and will come soon in one of the next alpha releases.
Your question about panning a background or animated cycle is also on our todolist. However it will probably not be included in this release (v 5.0) but in the next one. Stuff like panning is seen (by me) as a task done in compositing (outside Animation Paper). However, I agree it would be nice to have this capability inside AP, so … on the list. 😉
Best,
Niels
