Ability to have a file-system based folder in a project
One of my favourite features of IDEs like Eclipse or Android Studio (in
Eclipse's case, the only good feature) is how folders automatically keep in
sync with the project. Android Studio in particular does a fantastic job with
this, in that you can move files around using the file system navigator
(Finder), add images, rename them, add source files, remove them etc. When you
get back to the IDE after such activity, the project seamlessly updates itself,
and the changes you made are reflected, without having to manually drag and
drop files in, or right click to add files / folders etc.
I think it would be an amazing addition if you could add a folder mode to a
folder in a project tree, so that you could let Xamarin Studio know that this
particular folder is a file-system backed folder or a file-system mirroring
(If you could allow this but still retain the ability to add linked files /
folders, inside one of these tracked folders, you would be one-upping

If you manually edit the project file, you can use wildcards for this, though they are only refreshed when the project is reloaded.
