I hope we can still improve behaviour of dockers and toolbars .
In current implementation it is not useable to have toolbar and other window (eg. fx browser) in the same docker. As you can see in gif the toolbar size changes when fx window is resized and that messes whole layout. I would suggest to keep toolbars at their minimal size that allows to see all buttons.
Second problem (also shown below) is that at minimal toolbar size some buttons are visible only partially. I think it should be avoided.
Thanks
