Mind Traffic Control is ruthelessly useful. Indeed, it kind of strips out everything else *execept* usefulness.
Which is why, if you're thinking of trying it out, here's a hint. Don't try by putting in some random fake items like "test 1", "test 2" etc.
All they do is sit there and remind you to do them. You can't fiddle around organizing and prioritizing them, dragging and dropping or attaching little icons to them etc. (Which is the point.) So MTC looks inert.
In fact it *is* inert, because you don't really need it. MTC does nothing, because you want nothing from it. You don't really have a task of doing "test 1" or "try out mind traffic control" so the computer can't help.
It's as if Mind Traffic Control magically knows when it's being useful and when you don't really care.
So, to get the real MTC experience, put some real tasks in. Just 3 or 4 of the things you actually have to do over the next couple of days, and leave it open in a browser-tab on your machine.
Then MTC feels wanted. And the magic kicks in. ;-)
