This beta is close to a finished app. I have added the file and exit confirmation, it remembers its zoom settings, search options and search and replace strings and the Window menu to swap between instances is working as well. It creates its own configuration files on initial startup and if you manage to mess them up for any reason you can just delete them and it will create a new default set. The "Edit" menu has two settings options, one to set the editor font, the other is a couple of integer settings that need to be set manually to the users preference, the toolbar block indent in spaces and the screen startup size as screen percentages.
