   Well, I find it a bit annoying, that almost every time I edit a Yaml, HCL 
file, there is a flickering on the mouse cursor changing to wait cursor and 
then back.
   
   It turned out that is because the navigator is expanding it's tree to the 
current location, so when the structure changes it issues an expand and the 
`TreeView.autoWaitCursor` is `true` by default and put the cursor in wait mode 
for a brief moment.
   
   That led me to try other parts of the IDE, and expanding nodes could result 
with a brief mouse cursor change. That made me think to change the `TreeView` 
behavior. It would be good to have the default for the wait cursor to be 
`false`, though since it is down in the core I think it's being used many 
places outside of NetBeans.
   
   Probably the best would be delaying the wait cursor change by 500ms or so, 
and if the tree could expand it in that time we just do not do that. Might try 
to create a PR for that one, however for the default CSL provided navigator, I 
do not thing that we need the `autoWaitCursor` functionality at all.
