Yay! my refactoring to use the DataSet class worked great! So I have all the edit operations bound and working.
What just got done tonight:
You can now generate, edit and save dungeons done in DunGen and load them later in the same browser.
What's coming next:
Description editing is still at its most rudimentary in a prompt box for proof of concept. This is not too useful for long descriptions. Will expand to a full JS dialog box from some library. Will probably also add inline editing in the table.
