I have now finished my first test. This was fun, I look forward to my next project with Antetype. Keep up the great work guys, I really hope this is going to come out of beta soon. 99% of everything I did already worked flawlessly. If you can fix the break points, this is going to knock everything else out of the park. Most prototyping apps out there are very well suited to doing mobile app designs (which I haven’t even tested for Antetype so it may very well also be good at that!). When it comes to good old honest-to-god desktop apps, there is very little out there that is capable of competing with Antetype. Admittedly, floating and resizable windows need a bit of Javascript but the fact that you can use it, together with CSS, makes for a very powerful tool. I was able to knock up this prototype in a few evenings/weekends, starting from scratch and I can honestly say that this would have taken me weeks of hard work in Origami.
Thanks for your help @tim @fizfaz @dominic.lill.
