extending screen real estate on mac os

As I was struggling to make my paper write-ups more efficient, especially in cutting the time wasted in tabbing through numerous open windows and applications (common culprits being, MS Word, Bookends or Endnote, Papers, Skim, SPSS, Pathfinder - not to mention Mail and Skype!), I decided what I needed was an additional monitor which gave me more desktop real estate and allowed me to view at least 2 or three applications windows side-by-side. I also remembered this Randy Pausch lecture on time management and his take on multiple monitors. So, I ordered a Samsung LCD from ebuyer, okay its only 19" but I have a small desk at home and the monitor was on sale too! As soon as I got it and plugged it in, I though it would just extend my laptop monitor towards the side, which it did (and luckily for me, I placed my new monitor on the right side - the default side a mac seems to extend its display!).

However, what I was hoping was the top menu bar to extend all the way to my new monitor so I could get extended menu bar real estate too. Well, how wrong I was. And after Googling for hours and searching all the mac forums that I frequent, I couldn't find any tips or tricks to extend that menu bar - nothing! I know I can mirror it (by mirroring the main laptop display), but that’s a waste of external monitor as far as I'm concerned. I don't know why no one has come up with a program that let you extend the menu bar!?! dejamenu Anyway, what I did come across was a cool little application called DejaMenu, which gives all the menu items from the application you are running as a context menu on the press of a hot-key combination. At least this is much better than having to move mouse all the way to the main screen to get to the menus. I'm using DejaMenu now and I can't thank the creator enough for this wonderful application. Thank you!
And please someone make an application that lets us extend the main menu bar.
