So I tired Pokki... and while i like it, i am upset with it.
The developers make use of a "dirty trick". Pokki is designed so that it is always the first app right behind the start button. Proof? Ok, see the attached picture.
This is done by programatically extending the area that the start buttons sits in, enlarging it to the size of the start button + whatever Pokki apps you may have installed. You can see this by seeing the graphics discoloration between the pokki/start button area, and my next in line, real, pinned taskbar icon.
As how many people, when seeing screen shots, associate that the icons closest to the Start button is, indeed, an important, and therefore, must have app... This is what gets to me. You cant change it's location. Drag and drop re-arranging does not work. As a secondary note, it's a compiled javascript app. While not areal language, it's better than a "webapp", although, really, thats all that it is. some HTML/5 and javascript inset into a compiled exe.
Let me make one thing real. Webapps are not real apps. If it cant be nativly compiled, then your wasting your time. But thats just my line of thought as a serious, freelance developer.
Anyway, Pokki needs to add in some code that lets it be dragged and dropped away from the start button. It is useful, Oh My Yes. Does it need more work? OMG Yes.
