For projects I've been working on, I used various GraffitiSuite classes. These classes are an awesome extension to Xojo and work very good.
In the past I needed an extra class Anthony reacted quick and the new class was rock solid. Bugs are also solved quick and good.
Now whenever I need a certain class, I always look in GraffitiSuite first before looking for another solutions, but I will not hesitate to ask Anthony if he can add the class I need to GraffitiSuite.
GraffitiSuite for me is the best extension to Xojo.
