|Message:||...Er that's a bug in the webdesigner :-|
As a workaround, to create a new app, copy an existing one. Do this by clicking the little icon on the right of the app name (on the main screen). You can then delete the existing design elements from the copy.
I'll post a fix to this in the next few days.
The whole webdesign.pma is very bare bones and I'm hoping to make this look much sexier in the future :-)|
