Several productivity apps I added to this list in the last month.

• HazeOver - automatically highlights the front window by fading out all the background windows.
• Hazel - watches whatever folders you tell it to, automatically organizing your files according to the rules you create.
• Bartender - lets you organize your menu bar apps.
• iStatMenus - adds system monitor to your menu bar.

For iTerm2 I failed to setup Automatic Profile Switching, but I found a good solution here - Change terminal color when SSH from OS-X.
