Not every feature needs to be supported, which feature are you referring to? Also, given the use case: what is required in your opinion? How does the shift in microsofts scope translate to the efforts to sciter? What did the shift imply?
> sciter is good if you looking for make a small app which not depends too much on web spec.
Since when is it a feature to comply to "web spec"? Why should anyone continue to comply with all new requirements? And why do you feel it is required for portable desktop applications? Why not settle on some proven essentials? And why I am talking about browser now?
Hopefully you elaborate your thoughts: I am sincerly curious about your opinion.
