Toolbar in the way
Please dock the toolbar to the side at all times. I do like the new toolbar, but it blocks text on the PDFs, meaning I have to take the time to pan and zoom and adjust just to read what it is blocking, it's just unnecessary. Just have it docked always. Also, I will say I'm not the biggest fan of how the thumbnails are shown, but that's a different and much less important issue. The new "floating" toolbar (that you cannot move) obstructs the documents and should just be docked to the side so you can see an unobstructed view at all times.

We are hearing your concern, just to make a statement here that we have made the Quick tool bar floating, now you can place the toolbar anywhere in the document area(using the top bar in the Quick toolbar, Hold it long and drop it)
Also, to retain the positioning of quick toolbar, across all the documents, check the preference > Documents > Restore last view settings when reopening the documents.
Hope that helps.
