Comment 7 for bug 1524370

Clicking the icon should start the (settings) interface (I assume it does), in which you can make settings, preferred effect, time settings etc. Once that is done, the background script does its job, and notifies you when the break is "upcoming". That is the intended behaviour. I can imagine you'd like to see some kind of continuous presence in the panel or tray in any form however.
I added it to the "Whishlist". Thanks once again for taking the effort.
