I intend to use only Spark components for future projects. Migration of older projects would depend on project scope but I am sure it will happen for some.

I agree with Ryan’s comment “In actionscript the hints should be dictated by the import statements. If they don’t exist yet, set the default based on whether “preferred components only” is set.”

For new projects, I don’t see any reason I would use Halo components that have Spark counterparts unless they lacked some key feature. But even then the new architecture should make it much easier to add that in, right? ;)

I definitely can see myself porting some older projects, especially ongoing open source stuff.

I like the idea of the “preferred components only” setting assuming it is turned off by default on old projects and turned on by default on new ones.

When I type “Button”, I only want to see one choice. To override that, make me specifically type mx:Button or s:Button. In actionscript the hints should be dictated by the import statements. If they don’t exist yet, set the default based on whether “preferred components only” is set.
