The Properties Tab currently only has a General category. I would like to see us have another category where we have identified the most used jQuery/jQuery mobile widget properties such as:
id (always at the top)
data-role
data-icon
data-iconpos
other data-* set of properties
value (for input fields, value is pretty important)
type (for input fields, critical)
placeholder

The available properties can be more extensive than what was originally shown in the wizard/dialog when the widget was dragged from the palette. Any property deemed important enough to show in the wizard/dialog should also be promoted into this new category.

My proposal for the category name: jQuery
