Zinnia is a simple app and has this simple ability, along with the ability to be able to turn clip art and elements into hyperlinks that link to both the document and outside links I don’t understand why Goodnotes has not got on board please please please make these features available immediately. Turning pictures and clip art into links to different pages makes it so fun and beautiful to use any e journal. I think it is essential for creativity as well. Also the original request of locking layers Like making an element or clipart look like it’s coming in and out of a box just with the ability to be able to lock certain layers!!!!! GoodNotes is a place for study and creativity and it would be more so with these features please implement ASAP!!
