Use case or problem
The default behaviour when opening a file is to replace the current/active open file with the new one, which gets more irksome every time.
Proposed solution
Add a configuration option to change the default behaviour from replacing the currently active/open file to opening the selected file in a new tab.
Current workaround (optional)
I have to remember the app is going to screw me over and instead right-click on the file I want to open and explicitly chose “open in new tab”
