In Unity if there are lots of things pinned to the dock, the dock becomes "spongy": hovering over the bottom of the dock automatically expands that portion of the dock.
Can the Ubuntu Dock in 18.04+ behave the same way?
The issue I am having is that I have 15 or so items pinned to the dock and the last few ones cannot be accessed because the dock has no more visible room. I could resize the icons, but they become too small if I want to fit all of them.
