Improvements to date-based search

[benetti-marco]

When I perform a search by date, the rows modified since the specified date are highlighted.
It would be useful to:

• Have a search option that lets me find the rows modified on a specific date, not since a date.
• Be able to easily move from one modified row to another, using buttons or a keyboard shortcut (when the source has many lines, having to scroll through it to see the next highlighted lines is very inconvenient)

Thanks
