**Feature Request**
Brief title for your desired feature: Add spinner when rebuilding nets, drc errors
How would you like the feature to work?
When refreshing the netlist (in PCB) or the DRC error list, it can take some time. Some kind of indicator such as a busy cursor or a changing the refresh icon to a spinner would be useful.
Why is this feature important to you?
It would be nice no know when a refresh operation is completed. Currently, I have to park the cursor over a dropdown menu so that I can know when the program is ready again.
