Expand - Colapse with more than just clicking on + / - in a data view web part

SharePoint and FrontPage have a very nice functionality of grouping the data in a list data view according to selected group. What in my opinion can be improved, is that you expand or colapse the group with a click on the whole cell rather than targeting that small plus or minus sign in front of a group name.

Not to reinvent hot water again: this is already discovered so let me point it out:
