I think that WA have maybe created a bit of a rod for their own back by bundling extensions together (i.e. Validation is available in SA2, Form Builder etc but they are currently different versions!).
I do love the WA extensions, and they save me so much time, but I'd like to see the installs as separate extensions and if you buy CSS Form Builder then you get access to say 3 or 4 extensions in the download manager.
I think that WA are also going through a bit of a transitional phase with their extensions whilst they bring everything in line with the new file structure. I think they will come good but appreciate that it can be frustrating at time when extensions fall over, usually in the middle of a project :-)
Keep the faith.
