or a decent date and time picker.

drag and drop grids…
an easy way to include jquery or any other scripts into your project, maybe a simple paste your script or upload file and its automatically included in the entire project…
and an easy way to update parent page from modal window…
shadow effects in the css styling
more css3 options.
yes I know your gonna say these are 3rd party, then isnt it maybe about time u change them or upgrade them yourself…
For sure some of these are quite simple to implement no? and would add some great new features which really should be common as muck today!
just some food for thought
