If you have already built your first PhoneGapp app with Dreamweaver CS6 you should have already come across the problem: The config.xml provided by DW is really poor.
This extension replaces that file by another one with all the available options for it, and they are also documented so:
1.- You don't have to visit PhoneGap's site to find them
2.- You have the documentation for every option included in the file
3.- You just need to uncomment the options you are going to use (and edit their attributes if needed)
4.- The file is not included in the app, so its size is nothing you should worry about.
What will extension won't do:
it won't give any visual option to edit the file; you have to dig into the code (however, it's documented, so it shouldn't be an issue)
Requirements: Dreamweaver CS6
UI Access: none; the file is automatically added by DW when you create a new PhoneGap project.
If you don't want to install the extension, but you'd like to have the xml file to add it by hand, you can get it here.
