Settings
Cloze Overlapper comes with a simple Options menu which you can access from Anki's main screen by going to Tools → Cloze Overlapper Options...:
Clicking on Ok will apply the settings. Hitting Close or closing the window will dismiss your changes. You can revert to the default options by clicking on Restore Defaults and confirming with OK.
The entry fields provided in this section are the one and only way to rename the listed fields. As the add-on needs to know which field names correspond to what data you will have to use this dialog to rename the default fields. If you rename these fields through Anki directly it will cause the add-on to stop working, prompting you to change them back.
Please note that this only applies to the default fields. Any fields you add manually can be freely renamed and rearranged in any way you wish.
