The auto-save button is located in the upper right corner of The Compleat Botanica.

The auto-save button

Whenever any change is made to a specimen record, this button momentarily lights up. This is an indicator to you that you�ve made a change to the record. If you want to force these changes to be saved to the database immediately, just press the auto-save button. Normally however this explicit operation is not necessary because your changes are automatically saved to the database whenever you navigate to a new view.

A dimmed button is an indicator that everything has been saved.

This indicator status works the same way for the Filters, Checklist, and Category views as well.
