Email is such a important part of our daily lives and having your email do what you would like is so important. With Gmail you can customize it with Labs. I know in previous threads we have talked about this before however there are new labs out there so you might want to check it out again. So if your are not familiar with Labs you can kinda think of them as apps for your Gmail.
At the top of your Gmail click on the green hourglass or if you don't have that then click on "Settings"
In the navigation bar on the left-hand side of the "Open" and "Save As" dialog boxes there are options like My Recent Documents, My Documents, Desktop etc. This is convenient for when you open the same files over and over. Here's how to add one of your frequently used folders without having to navigate all over your network to find it.
Go to "Open" or "Save As". In this example, I want to add the folder called "Reports" I use this reports folder a LOT (which contains subfolders)
