For those who think that FileMaker Inc isn't listening to the community, here's proof to the contrary:
Terry Barwegen, the Senior Product Manager at FileMaker Inc, took time this afternooon to read and respond to a somewhat critical blog post that I had written about WebDirect ("FileMaker 13's WebDirect: I want to like it. I really do."). In his reply, he addresses the printing issue, performance and hardware requirements, and more.
Also, this has been mentioned before, but it is worth mentioning again: If you have FileMaker feature requests or suggestions (we all have wish lists, don't we?), then head over here and let FileMaker know.
