QR Code generation isn't nearly enough to some premium subscription with Corel. Besides, if I need a QR code I can generate one for free at a number of different web sites, such as
http://qrcode.kaywa.com/. Font playground feature? Meh.
IMHO Corel goofed up a lot more than they fixed with the X6.4 update. I simply cannot stand how the font menus work in X6.4 now. They need to change that. On screen type performance is now even more laggy than it was before. And I'm using a new quad core Core i7 PC with 24GB of RAM running Win8 Pro.
I like to gripe about Adobe using strong-arm monopolist tactics on its customers with Creative Cloud. But if Adobe's rivals, such as Corel, can't get their act together Adobe will have complete free will with abusing its customers further.
