I much prefer cropping my Photos in Photo Mechanic to LR because there is no lag, however, it is quite annoying when many of my photos need to be cropped and straightened by just a tiny bit, this means you need to start dragging out the crop all the way in the corner of the photo
How difficult would it be for camera bits to add a crop box overlay by default (when in crop mode) that a user can simply straighten or crop there photos without having to draw a marquee crop over the whole image. (Similar to LR)
Lastly, maybe this would be asking too much but would love the option to set cropping hotkey presets, for instance in LR if you press "X" (in the crop module) the crop box will switch from horizontal to vertical or vice versa.
