Hi everyone!
The green check mark on every file icon is, of course, not a required, critical or even necessary part of the program. I know this because I've now gotten rid of it. Dropbox still works - Amazing! The great thing is, Dropbox will still tell me if something *isn't* synced, which is actually a really useful shell overlay to have in place.
I'm also not going out on too much of a limb to say that the Dropbox reps on this thread who are feigning confusion of offering to pass this off to the devs as a new feature suggestion are being disingenuous. Dropbox knows a significant minority of their users really dislike the green check. Don't expect them to add disabling the checkmarks to their "new feature" list. They could fix it in 2 hours if they wanted to; they don't.
Fortunately, after quite a bit of searching, I've found a a way around their stubbornness. Nirsoft has a free tool called ShellExView; download it and you can disable the synced file green check shell overlay icon. It will show up as DropboxExt1 Class in the list. You may need to do this after every update.
