As currently written the plugin defaults to the same folder each time I run it. This is not convenient. There is a very good chance that I will want to go back to the same folder each time, so I added the exported file path to the defaults that are written to a read from the prefs file.

As part of doing that I changed -defaultDirectory to this code:

Here I check to see if the value read from the defaults (_defaultExportPath) is a valid folder using NSFileManager. If it is, then I use it, otherwise I use the built-in default of ~/Documents. This deals with the user moving or renaming the folder between runs.

Another change I have made is to make the Generate button do something. I decided that using the current date and time would make for a good salt value:

And here is the latest interface:

Note that since I am posting this after the plugin was released, this interface design is no longer current.
