Very excited to see v-carving finally on the list! A bit surprised to see the paid version, but 4 days free is a good shout and sure that’ll be plenty for most people.
Anyway, now Easel has the ability to do half-decent signs there are 2 major but simple features I think you should consider:
A list of available fonts with their previews on a webpage so that businesses can direct clients there to choose the font for their sign. A downloadable PDF would be fine too, preferably with minimal branding on it.
The detailed preview is great but we really need to be able to send the client this preview before confirming the job. I currently (and very cheekily) use the free trial version of Vcarve to do this, and then use F-Engrave to run the job!
Looking forward to having a play once I replace my blown x-axis driver!
