This is frankly the worst-looking application I've seen in many years. It looks like a bad OS9 app. No; it looks like a bad OS8 app.

Perhaps it performs well; I don't really know. Due to its unseemly appearance, I simply wasn't the least bit interested in determining how well it performs.

I gained quite a bit of insight when I checked the developer's web site to see if the app has particular features I need. Links to the online user manual for detailed information revealed that PDF Studio is a Windows application that has simply been "ported" to the Mac platform.

I don't have a problem with that, in theory. Other developers have successfully ported applications from one platform to another. No problem! But in this case, no effort was made to make the application attractive or to make it look like a Mac app. (Or any effort that was made was 100% unsuccessful.)

Although on the surface PDF Studio appears to have more features than Smile On My Mac's "PDF Pen," I'll live without the extra features in order to keep working with an app that's a pleasure to look at (while working).
