Suggestion: All controls should have progress bar (no replies)

Hi,

I think All Controls internally should have infinite progress bar.
calling it same like grayed out by enable the property.

Control..progress = true -> control become disable and on top of control appear infinite circle progress bar
Control..progress = false -> the infinite progress bar disappear


when one control with ..progress = true, use cannot click that control but user can still click other controls . but if it's mywindows..progress = true then all controls in that windows become disable.

what do you think ?
