Mac OX X irritants

I just started working on Mac OS X 1.5 and hit some major irritants which needed work-around:

1. Mac OS X (at-least 1.5.x) has no easy way to display date and time in the menu bar. Followed instructions at MacInstruct website to copy the date format and paste it in time format. Note: I had to change all the time formats (short, long, medium, all) before making it work. I also had to go back to clock menu and remove "Show day of the week". Can't figure out how Mac hasn't solved such a big usability problem so far.
2. By default you can't use tab in firefox to focus on drop down menus. This is easy to fix. Just need to go to Mac Preferences->Keyboard & Mouse->Keyboard Shortcuts and check "All controls" at the bottom under "Full keyboard access" topic.
