Clicking on the icon will open the Scheduler window. Scheduler is located at the top of the IDM window.
Scheduler, true to its name, schedules downloads, and Grabber grabs multiple downloads from a web page. Many people who use IDM might not be familiar with the additional features it offers, the major two being Scheduler and Grabber. Sure, there are other download managers for Windows, but for me, nothing is as good as IDM. Internet Download Manager is one of the applications I swear by.
