I have been using Mac OS X Loin since two months and feel that I can't tweak the Dock much. For Example, I am unable to stretch the Dock to 100% width of the screen.
My Idea is something similar to windows classic task bar (or gnome2 panel). Do anyone of use is aware any app with such options? If not then is there something else you prefer over Mac OS X Dock.
Many OS X users just keep the Dock hidden and ignore it most of the time. You can use ⌘⇥ to switch between active applications and quit them. Other apps can be opened with Spotlight or third party launchers like Alfred, LaunchBar or Quicksilver. (Or keyboard shortcuts.)
There are a few graphical launchers and Dock replacement apps, but none have been that popular. (See osx.iusethis.com/tag/dock.) There was one app that aimed at providing something like the Windows task bar for OS X, Fantastik, but its website has been taken offline.
