Thank you a lot for the feedback.
You can change the upload server directly on the photo, still a bit limited for now, it will be more flexible once I implement blossom (which I am very in needed right now)

Lots of deck features will come eventually, specially around column widths and reorder, note font size is a really good idea, I wasn't thinking about that.
I hope i can get NWC around next month, trying to fix all the small issues right now instead of adding everything at once
