+1 here too.
I like it the way it was before (toggle osnaps, while MEP snaps stay on). I've never had a reason to turn off MEP snaps on-the-fly, but I'm always needing the ACAD osnaps out of my way temporarily, while still using MEP snaps.
Is there a way to code it such that we can leave ACAD osnaps on F3, and configure MEP snaps for a function key that we don't use... say F4? I know some people use tablets, so I don't suggest a universal F-key swap, though I'm all FOR it if that particular toggle is obsolete.
