When I click on a file in the tree, Sublime 3 opens it in a “temporary” tab with an italicized title, and if I click on another file, replaces the tab. The only way to turn the title into ordinary text and keep the pane open is to fiddle with the tab or the file sufficiently that Sublime decides that I really want it open.
I want to disable this behavior and keep tabs open until I close them. How can I do this?
