Hi,
I've just had a short glimpse at the trial but these things would make this tool great for UI design (forget Sketch because of performance):
Paragraph and character styles Automatic style updating or some easy-to-use alternative Different artboards in one view to design flows Easy-to-use symbols to complement the outsourced embedded files
In the help it says:
Am I missing something or text attributes are not part of styles?
Please include this on the roadmap and the tool will finally destroy Adobe :P.
