Designer - anything ("rudimentary" features) planend like this?

[Polygonius]

I´m a owner of AP. And i´m really happy with it it, for the main-resaon i bought it (Photo-stunts). I alos like AND use its "design"-features" for my normal "needs". But as love my "design"-features for my normal needs, as many i miss "special_features" for my "jobs": Creating VSTs "elements".... In this case, so far i do not see any reason to buy AD too, for "my" design-jobs too!  But if Serif is planend to integrate a functionality-pack like the FREEware JK KNOBMAN (Its a special app for VST...etc... GUI-Desgin with "automatically animated stripes", like knobs, faders, multi-text-"single"-frames.... especially useful for creating "animated" elements for VSTi - GUIs and other music-apps....  i would be the "predator" and would buy AD for the double price... But without this... i dont see any reason to buy AD, because most of my "GUI" stuff AP and AD seems to be as same "good" or as same "bad". I cannot understand why Serif dont see/deliver this semi-big-market "VST_GUI-Designer"!  To devolop/implement thinks like this... ONE private-guy was able to write a tool, like this, for almost 10 years years and offered it for FREE. But a (almost) big-player-company is not able to just translate (not even create) his brilliant one-man-show into its own apps-languge?  i cant understand!
