Hello. I think too that WM is a very good solution and need more marketing to be considered as a competitive solution by the author community (in France at least).
A Mac bundle (dmg) available or not in apple store should be a good first step: I tried to convinced mac users authors to use WM, but the relative difficulty to initial start up is a real break to the acceptation.
A user friendly cloud solution would be a second important step.
Regarding iOS or android app I understand it could be complicated and time consumming to start a project. So bad, it would be great. :)
