1. Open an alloy view with App designer 'Scratchpad editor'
2. Go to XML section(2nd tab) of the editor
3. Hit 'Ctrl+Space' to see intellisense proposals based on the context
4. Scratchpad XML editor is not showing any intellisense proposals
I believe Scratchpad XML editor should exactly work like standard Alloy View XML editor so that users needn't switch between Alloy view editor and Scratchpad editor
To do this, studio has to expose Alloy view editor functionality and packages to the VisualUI plugin
