Hi,
My SQL Developer is 19.1.
I'm navigating from one package to another because of many nested references, and time to time SQL Developer hangs on "comparing subprograms", such as the one shown in the example below:

I don't know why it's comparing, but it causes SQL Developer to completely hang, freeze, or even "blink", disappearing from the taskbar and reappearing, and the only solution I have is to Ctrl+Alt+Del SQL Developer, losing all the open package body I had.

That being said, it would nice to have a "restore" options to retrieve all my pages that were open at the time of the crash.
Thanks
