From what is understand a common frustration amongst some designers are design prototype iterations.<p>They would have to prototype designs and send it to clients who would then have to approve the designs. But because there's no streamlined way they know of, links sent to the client usually gets lost or the fact that they're links and do not show the prototypes it's easy for the client to "get back to it later".<p>I'd like to know if this is a common problem for you or do you have similar problems that weren't mentioned?<p>Thanks
