Don’t know if it has already been suggested but I’d like to see the BrowseDialog search criteria support a DatePicker control for date fields.

I also need "between" range search feature. Has it been implemented? If not, any workaround?

Thank you

To implement a "between," you can add the search field twice... one with a "Greater Than" option and one with a "Less Than" option and turn off the Advanced Options for both of those fields.  Then, your users can just select the start and end values for the range.
