This is also something I've wondered as well... :confused:
Whenever I've tried Importing using this option (or any other method I could think of), I've always come across problems where elements such as styles etc. aren't brought across when you do the Import. It would be great if Imported elements could adopt the style of the project that is being imported into at the point it was being imported?
What you end up doing after the import is sooo much work to get the window/element working and looking as you want it - you could have created the window from scratch (or from a template) and just cut-n-paste the code across in less time?! [[5]]
...but there's always a possibility that I'm missing something?
Does this match other peoples experiences with importing external elements?
