I open a document in edit mode and change a date. - Nothing more.
Leaving the document with <ESC> I sometimes am not asked if the changes shall be saved.
I mark part of the date, like the month, with the mouse and replace it by just typing the new month ...
I would like to see the support of, beyond "yesterday" and "tomorrow" and "today" also see support for "+2" or "-3", to make it take todays date +2 days or similiarily "3 days ago" when entering dates in the date fields.
