I'm glad to see this has finally been made an option!
I absolutely *hated* it when it got arbitrarily changed from "to the right" (which was the original default, back in an earlier version of VS) to "to the left" (without a way of changing it back again for those who didn't like it).
When I complained about it I was told that it was a 50/50 thing, that half developers wanted it the new way & the other half wanted it the old way.
Back then I wondered to myself why on earth it was just changed "out of the blue" like that in the first place, & wasn't made an option from the get go, or at least when it got changed.
Nice to see it's FINALLY been done right.
