I great feature for Antetype would be to Link a folder for the Resource Inspector.
The idea is then i start a now antetype project, i can link a folder to this project with all my files which i need in the Resource inspector or then i safe the Antetype file in a folder, i can create a folder "assets" and in this folder i can collect all pictures for a project.
For example i am working on a project and i can easily paste many files in these folder and then they are included in my Antetype project.
And after, then I edit one and replace the picture in the folder Antetype automaticly updates these file.
Nowadays i must go in Antetype, Drag and Drop the file manualy in the Resource inspector.
Then you know the Wireframe tool, Balsamiq Mockups, you will know these function.
