Finding Text in Versions
It is conceivable that you want to choose a version to be restored according to whether it contains specific text. When you use Dolphin to restore a version, you can select the Find tab which will allow you to enter find criteria for the text pattern, wildcard, or regular expression.

The versions along with line numbers containing the text will be shown, allowing you to select one for either preview or restoration.

A “context” setting allows you to also see lines adjacent to ones containing the text.
