I can't find any difference between Logi Options and Options+. There's no new customization options, we're still stuck with only being able to customize the top row keys instead of the whole keyboard. I can't tailor CMD/ALT behavior and Key combination functionality. I can't switch Win/Mac functionality on a per application basis or remap to support CMD+X/C/V in windows and similar situations to get consistency in my keyboard between the two OSes. And I'm still stuck having to toggle my mouse and my keyboard separately to switch computers. And while I haven't yet tried FLOW under options+, the functionality in Options was horrid with multi-second switching delays.
