I am new to Mac and am looking for help customizing my new favorite toy. I have been looking at widgets and just about all the ones I have seen do not look like anything I would ever want or need. I did find two so far that I know will be useful. I do not remember the names, but one of them shows the performance of my MBP. it was recommended by someone here (Thank you) and works great. the other one is a widget to track packages by tracking number. So what are your favorite widgets? Which are the must haves?
