Hi,
I'm using the paid verson of sketchbook pro for android - version 2.9.4 (#433023) on my tablet NEXUS (2012) + stylus pen (rubber).
It's a tremendes drawing application. I left Photoshop / Illustrator behind and discoverd a new world of creativity aid!
I draw freehand, most of the time. But I'm using the "Tools" too. The guides "Ruler" and "Circle" are practical. But....
It would be handy to have a tool like "Bezier" or "flexible" guide, so I should be able to prefix a curved line (limited length) and use that guide to draw a perfect shaped line. I think that two endpoints and one middle-point would be sufficient to shape that guiding line.
Maybe it's possible? Just an idea that came out when using the guide-tools.
Thanks for your attention,
Regards!
Good luck with Sketchbook Pro!
Christof.
