Absolutely Must Have Programs?

[tsbrewers]

I thought it would be nice and handy to have a list of Must Have Programs, or ones you really can't live without.

1. Try to keep it to one or two programs that you can't live without,
2. Please write a SHORT reason why you feel this way
3. If possible, either leave a link to the program, or to a thread with it.
4. No ROM's, those are fairly personal and people should check out entire threads before jumping.
4. If it is a visual enhancement, please show a screen capture or link.

I will start,

Smart Phone Tracker- send a text to your phone and it will email back the phones location via gps. handy if you lose the phone and are trying to find it.
