So.. As a Design tool, I guess you guys at least put something that designers familiar with. I am a UIUX designer and also have a little bit front end knowledge, I guess SVG import is a possible feature because html support svg.
This tool for me, is making a responsive design from pages of UI layouts from sketch (a software) to one responsive file.
In my mind, AI is for drawing, Sketch is for making UI, and Subform is making it responsive.
So, I think that building a product in subform from zero is not possible because you guys obviously do not and do not seems to support drawing, so hope you guys can help us to make it happen, and make subform more possible to use for a designer
