For now we have the ability to copy and add style to elements.
Could be nice to have also Reset Style to origin so the Element would get back to original Style.
This way would not have to go into all tabs to delete the style of the element
I agree, it would be beneficial to the ones who like me made a mistake styling id’s and now want to add a css class to all these items and have them all with once css class.
Have a look at Advanced Themer, it can do most if not all of this along with many many other great things.
It can copy ID styles to Classes and Erase ID styles.
