I think it would be a nice when a first item in a listview is selected when that listview is used as a source for a dataview.
Now the first item is selected, but it's not visible for the user.
See https://forum.mendix.com/link/questions/89615 for a dirty fix I tried.
there is a widget that does this, but I agree, this should be default behaviour, and good to see it being adressed in 7.22
Fixed in Mx 7.22
