I do it a lot, keeps it fresh. A lot of times I end up with an order I love and a lot of times one I really don't, and of course that doesn't stay for long!
I have one row that is pretty set in stone and hasn't moved in quite a while (and won't, much) but everything else gets moved around, at least for now. I move them all by force, definitely annoying to do, but I guess if you're young and ambitious...
