Merge almost empty Toolbars?

I do installed a lot of components, but I do want to organize a little bit better my components toolbar, because right now a lot of this components have only one or just a few components in them.

It is there a way to merge or change the location of this components into one toolbar or move them into another toolbar?

My toolbar looks like this:
GH_Toolbar_1
GH_Toolbar_2
GH_Toolbar_3
GH_Toolbar_4
GH_Toolbar_5



A lot of waisted space, meantime my Grasshopper window don’t fit in the screen to show all the components.
