@Retr0-XD thank you for the PR. I'm looking forward to reviewing this shortly. Can you please fill out the Pull Request template? Thanks again!

I compiled this branch (after adding the missing using) but it seems that middle clicking the title bar doesn't open a new tab.

Okay , can you tell what changes were done before testing this code change & if there errors popped on compilation please share

[yair100]

@Retr0-XD no changes were made to the code (aside from adding the missing reference). Did you test the changes on your end? If so, please update the PR description with the steps used to test the changes.
