- Auto-saving to disk: For maps on disk, you can turn on auto-saving. Just open the File menu and choose "Turn on autosave". (You can easily turn it off from the File Menu as well). This option is global - so it will work on all maps in the window until you turn it off.
- Save under a different name: You can now save a file as a copy, leaving the original one intact, by choosing the option File->Save As...
The new version of MindMup Desktop also makes it clearer which file you're working on - just hover the mouse pointer over the File->Save option, or over the file name in the Window top menu, and you will see the path on the disk where the file is saved.
The application will automatically update for users who installed it through the Chrome App store. If you've not installed it yet, head over to the MindMup Desktop chrome app store page.
