Yes, its rather frustrating. I do a lot of zooming in and out in architectural visualization and from time to time loose my place. It is very frustrating to model an item and realize you have been relying on grid lines that are mm apart instead of cm. I have no idea why something so fundamental to the work space is not dealt with. Things like positioning of icons and menu items and more cosmetic things seem to be of more importance than knowing at a glance what scale you are in… go figure?
Maybe it is just to much to ask people to take 20min out of their coding lives to restore a simple feature… Yep, that’s how I feel.
