@imsnif This is the original commit for the PR. There is one small issue: when editing the pane the title is update accordingly. But when closing the editor, the title does not get updated. It needs a refresh. For example, if I switch to another tab and back, the title is update back to "Pane #1". Any ideas?

I see also a test failing. I will fix it.

@imsnif So, I see that the tests are failing because of the title being different. Can you please explain me how the snapshot assertion is working?

Hey, @cosminadrianpopescu I'm sorry for not responding but I'm going on vacation and don't have a lot of time. I'll be back around June 24th and can reply in more detail then. Until then, there's some information about the tests in CONTRIBUTING.md - we generally use snapshot tests created with cargo insta.
