Suggestion to improve 'between' filter condition.

Related products: Windows GUI

When you use the filter condition 'between' you must always enter both the min and max. If you leave one empty, you will receive an error message. It would be nice if the condition would then automatically be adjusted.
When the filter condition 'Between' or 'Not between' is selected and only one of the two fields are filled with a value, the filter condition is changed to 'Greater than or equal to' or 'Smaller than or equal to'.
