Show visual for slideable divider of windows

This makes it clear that the windows cna be hidden.

As far as I know slideable areas are never highlighted, you will just have to find them by accident.
I don't think it is possible to highlight them. The only way would be by making these areas larger and adding some sort of arrows inside of them, but this defeats the whole purpose of gaining space by moving them, since you have to sacrifice space to add the arrows.

This is sort of a dilemma, because the user does not know he can drag it away, even though he would like to.

We could add a different visual for the mouse when hovering over these areas? For example the two-way arrow which is also shown when resizing windows in an OS like Windows.

This is not triggered by JavaFX, but by the window manager of your operating system. You will most likely already have this.

I do not understand the issue then
