Remember back when there was an iron grip on how menus were laid out? Remember when it frustrated us all that we had to use the same keyboard shortcuts to reach simliar functions? I miss those days. From the current nightmare that is Microsoft Office, where it took me twenty minutes to find the print command for the first time. To drilling down through three menus to find my bookmarks!
While you're at it, knock off that rapid release cycle! Version 12 looks just like Version 3, except that I had to completely wipe my copy of firefox, delete every single firefox folder on the machine, then had scrub the registry just so I could reinstall and not have weird errors and random things not work. Boy that was a fun way to spend my evening.
