For people who use Electric Drummer. If you accidentally close a file that's open and want it to re-appear in its previous position, you can edit your prefs.json file. You can find it by choosing Open Data Folder from the File menu. You'll see prefs.json. Open it in a text editor, and make the changes you want -- carefully. Probably a good idea to make a copy of the file before editing. But I just did it and laughed out loud, why didn't I think of this before? Heh.
