After going from 16.04 to 18.04 I noticed that there are a few things missing (apart from the obvious lack of the useful Alt+alt menu search)
- I install Netbeans 9 and when I run it, there is no right click and lock in launch panel... How do I keep it handy in the leftmost launcher? It also has awful simple looking checkboxes and tabs within Netbeans (Java?) but that's another topic.
- Middle scroll doesn't seem to do anything on the leftmost launcher. You used to be able to jump through all the terminal windows or windows of a certain app with the scroll wheel which is very handy.
