When we import a package, it doesn't seem their is a way to import the package into a specific folder. I prefer to have structure that is.
Their needs to be a selected a folder dialog to choose the correct format you wish.
When you import a package from the Asset Store, it can be a mess as sometimes they import it into the main Assets folder, so files are mixed with theirs and impossible to separate out.
Its nice if the Asset creators have a subfolder, such as 'Cartoon Soldier' has a folder which you can move into the Packages folder if you choose.
This INCLUDES offically unity Packages, some series, such as the SampleUI dumps files all over your asset folder, and makes it impossible to seperate out the specific ones for the packge, and makes it almost impossible to remove the package.
Secondary, tools such as import and export, should be notified if a folder changes so they can continue to work.
