I noticed with great surprise that Dropbox Sign would not only by default flatten PDFs where links were previously added, there is also no option to reverse/enable this. So that links would open in a new tab so the signee can check the links before signing a document, for example to confirm something. I get it that somebody may come up with some risk regarding security threats (but then again, how would there be a risk? Did it ever happen or did somebody THINK it may happen?). If we consider this for a valid reason: where is the difference between leaving links clickable in the first place, or to do this whole process to add Hyperlinks manually and inefficiently (which is possible currently), as also then, URLs would become clickable, only that it takes you a lot of time and is prone to error (e.g. if a few or many different links would need to be added). Anyway, it'd be great to give Users of Dropbox Sign the option to not have PDFs flattened.
