How to remove remember the milk from panel

Seriously, I never believed I'll write that stupid post, but anyway.
So, I wanted to try Rember The Milk to manage to-do lists and so on.
I added it as a widget to my top panel and tested it for a while. Then I wanted to remove it.
And as unbelievable as it is, I couldn't. There was no Remove Icon/Widget in the context menu. That freaked me for a while, but in the end I managed to remove it. The only way to do it turned out to be:
 Unlock Panel -> Add a new row to panel-> Move the unwanted Icons on the new row and then Right click on Panel and choose Remove Panel.
And yeah!
Oh well. It's simple once you know it, but I actually googled removing remember the milk, then googled where KDE stores the panel data, then checked the files in question, then realized it's too complicated to edit them and came up with this solutions.
Btw, if a good app for to-do reminders is Firefox "Reminder Fox". It works, it doesn't require registration or cloud services and it's easy to uninstall. And it's ridiculously annoying. Which is the point, when you want to set up a reminder, right? :)
Cheers.
