I do think it has uses beyond sewing; enlarging art, for example, or perhaps painting stage backgrounds, or maybe laying out patterns for building something out of wood.
My app is called Project&Cut and can be found at https://projectandcut.com.
Once you have a PDF, you can: 1 - print it in poster format across many pages of paper 2 - use a projector aimed down onto your cutting surface and then cut the pieces out or 3 - a few people are fortunate enough to use laser cutters to cut out their fabric.
Speaking more on point 2, projector sewing got way easier this year with the release of automatic calibration software, namely https://projectandcut.com and https://www.patternprojector.com. (The first one is my project). If you want to learn more about it, you might also look at Projectors for Sewing facebook group (https://www.facebook.com/groups/481078582801085) or https://projectorsewing.com or search google or YouTube.
You really can be set up for $100. I also think this could work with some forms of woodworking, or, say, crafting foam armour or decorating cakes.
But I take huge issue with some of the 'deliberate' limitations. No function returns? No way to share code blocks? These are some of the fundamentals of code.
In my experience these limitations present a big barrier to kids who want to just get some things done, and teaches a very hacky style to those who are willing to learn the complex workarounds to overcome the barriers. Ultimately it leads to the majority being 'confined' to doing typical simple scratch projects, and a small 'elite' who go beyond. Possibly the opposite of what was intended.
Is such a thing possible with the Linux market? Can I sell my software through stores? Is IAP a thing?
Are there other all-in-one platforms?
It reminds me a little of Citadel/UX (https://citadel.org) or software for the Reticulum Network (https://reticulum.network/manual/gettingstartedfast.html#nom...).
