Thanks for implementing this! I found myself in many situations where I've marked up something on the screenshot and then accidentally quit editing it...

I've tested this and I can confirm that it's working as described.

@borgmanJeremy @mmahmoudian please also take a look at this one 🙂 I have been using this PR along couple of others for a month now on my daily basis and I can confirm that it indeed gets the job done.

This also addresses #2055

The code is clean and looks good to me. Just as a very minor suggestion: maybe hardcoding the color can be changed to something dynamic to katch the overall theme that the user has configured?

Let's wait for other devs' approval.

Thanks! looks good to me. Would you be able to rebase on master to trigger the CI? Then I can merge it.
