First off, I suspect that this is a bug, but if the described behavior is intended, please move this topic to 'suggestions for changes'.
Anyway, suppose I have the follow toolbar layout.
Now, I decided that I want the transport belt in spot that is now in spot #2 in spot #3 instead. In the 0.16 toolbar, clicking #2 would put the transport belt in my hand. Dropping it on spot #3 would erase #2, put the transport belt in #2, and instead put the underground belt in my hand.
This no longer happens, and it makes changing filters on the toolbar way more cumbersome than it used to be, almost offsetting the gains by having the toolbar act as a filter (which is awesome, btw).
Instead the aforementioned procedure leads to this:
As you can see the transport belt is still in #2, and the underground belt has moved to my hand.
To replace a filter, I now need to for example click #3, put it in an empty spot, then delete #3, then move #2 over to #3, and then delete #2. This does not feel like it matches the UI philosophy that I've been reading about in the blog posts.
Thank you for making great games.

This is by design, the quickbar does not behave the same as inventory slots, and setting/clearing slots is more explicit
