I'm currently using Affinity Designer and trying to do some User Interface Prototyping. I only just started using the software, so maybe Symbols aren't the right tool for the job.
To clarify, I'm not actually creating a Symbol directly from a Text object. Rather, I'm grouping together a bunch of objects to create something which resembles a list item and then creating a Symbol from that group. I'm then trying to change the contents of the list item while maintaining the ability to style it.
I might play around with Text Styles tonight and see if that goes any better.
If there is a better way to do what I'm trying to do, I'm all ears. I'm just hoping that I can use Designer to prototype a little more rapidly than firing up a browser and writing some code.
