How do we manage (delete entries in) the Backup Versions list? Did not find mention of this on the SiteDelta's schierla website.

This review is for a previous version of the add-on (0.11.1). 

Deleting page backups

SiteDelta does not contain any function to manage or delete page backups; you have to delete them manually. The backups are stored in a folder called "SiteDelta" in the user's home directory (e.g. "C:\Users\[Username]\SiteDelta" for Windows 7)
