Sketches in Knack

I've been using the SIGNATURE field to provide a (very) basic sketch function in a survey app I've developed for a customer. on a tablet or smartphone using the appropriate pen, it works really well although the area is obviously designed for a long, thin signature.

If we could make the signature field are bigger, or even user defined, it would be a brilliant quick fix and allow us to create and store just about any hand drawn element within the database. I don't think any other changes would be necessary.

Anyone like it?

Hi Andrew,

You could easily change the size of the div's involved to increase the size of the signature field.
