I would like to be able to put in "User Setting" options into "My Menu". I'm a wedding photographer so making sure my time and date are the same across multiple cameras and formatting cards are the 2 biggest things I change from wedding to wedding and the fact that I still have to go into the User Setting tab to change that just takes more time than if it was in "My Menu" like I could do on my Canons.
Also, I would like that if you are shooting RAW + JPEG that when you go into playback mode that it reads from Card 2 instead of Card 1 by default since that's where your JPEGs go, I'm constantly switching from Card 1 to Card 2 so that I can review the JPEGs and then wirelessly transfer them to my phone for uploading.
As another user mentioned, I'll 2nd the part of about when you're in playback mode that you can depress the focus lever to go to 100% especially when you can use the focus lever to scan around the image anyways, it's just more natural than clicking the rear command dial and then going to the focus lever to scan around, it would be really quick to have everything under the focus lever.
Also, I'm not sure why when you go into the Wrench icon that the viewfinder clicks closed. That's the only Menu that it does that with. Very weird and unnecessary movements to the viewfinder.
Battery percentage being displayed in the viewfinder would help!
Even with all this, I love my X-Pro2!
