Hi (first post dance)
TL;DR +1
I third the request to be able to work at high resolution and export scaled versions.
Bonus points:
I wonder what proportions of artists/animators create in vector then export bitmaps? Come to think of it, is there any chance we could import/associate SVG/whatever for use with the bones to generate different scaled animations? Guess only with an exporting script that hands-off the bitmaps for Spriter to work with?
Cheers, R.
