In the scalar properties window, it would help to add an "apply" button. Or to use the vanilla behaviour, which only closes the window when "done" is pressed; "save" can be re-used.

Although the vector fields window looks quite nice, would it help to see the vector structure as in vanilla? I can't rememeber the template's structure when checking out scalars, and I try to work regularly with data structures. Maybe an option to show it, or showing it as non-editable text outside the vector area.

It is a bit cumbersome to have to check the "edit vector data" box - the properties window should give immediate access to this information, it is as if it is inside another window.
