Something I recently noticed...
If you select multiple objects, for example basic button, then change a property, for example back color, it will change this property for all items selected. I was hoping it would do this, but wasn't sure until I tried. So, if you are looking for a way to quickly change multiple objects quickly, this may be something for you. If this is common knowledge, sorry to duplicate, but thought it may be helpful to others.
FYI, I'm using VS2017.
