Hi @bam,
why not just provide a simple class for getting the required inputs on sketch startup ?
The class below could be improved in many ways (ie. allow a range for values [3.14,6.28] or specific Strings (like enum string values), etc.) but guess it demonstrates the general idea …
Hope that helps…
Cheers
