There's a way to pin a panel?

For example, stop the f9 panel from disappearing.

F9 ? You mean the Outliner? Why is it disappearing?

See: Interface
and in particular: Areas

The information on F9 is temporary. The information is not maintained.

If it’s a problem with the F9 panel closing, you can bring it back to F9. And the location you’re showing is the mousepoint location. :thinking:

Specifically the Adjust Last Operation menu:

Enable View → Adjust Last Operation so it sticks to the bottom left… and only disappears when choosing another object.
