A place to store all your popular applications and files, sorted by how much you use them. If you pin them, they will show up first.
To add a file or application, you can locate it via Add Icon>Locate or just drag and drop it in from any file on your computer.
You can edit the name, if pinned, and delete the file by right clicking and selecting appropriate action.
You can also adjust how big the icons are by going to View>Edit Scale and enter a number between 1 and 4 times the original icon size (4 is super big).
BEWARE: major lag issues occur over time. I didn't have enough competing time to get rid of it. Sorries.
