I'm new to the Creator and am using it with a Leapfrog Creatr.
A few things I liked about Repetier, and what I'm missing in Creator, is the preview and of the printer moves in 3D while printing.
Another thing that confused me the first time I used Creator was: where do I set the printer that I have?
Now I know that per-job you'd like to change all kinds of settings, but for example build area etc are pretty defined per printer model/type.
Maybe an idea to link that up with the connection settings when one connects to the printer or under preferences?
A very cool feature would be slicing with the option to minimize jerking/slamming ... Creator already does a good job (when compared to slic3r) but it would be a neat option to have.
