MX 3 mouse is second to none! I use it on a PC and Mac with flow and just ordered the MX Keys. I noticed on the Mac, setting a button to screen capture, it shows more options like full screen or a region as well as location to save to, however it doesn't these same options on the PC version, just a screen capture. I LOVE the screen capturing the region option because a lot of times I want to screen shot just a certain section. it works flawlessly on the Mac and would be amazing if the PC can do it as well. thank you for everything!
