text: When you open a recent project from the welcome screen, the last one remains opened in a tab. VSCode Version: 1.9.1 OS Version: macOS Sierra 10.12.3 Steps to Reproduce: a new VSCode window. a recent project from the welcome screen. project is opened and the welcome screen remains opened.
The current behavior was chosen in the hope that this would help new users by staying in the same context.
I agree that the welcome screen should be closed after taking an action from it. Especially in my case, where I prefer to use the setting, having to close the otherwise empty welcome window after opening from the 'Recents' list or via FileOpen feels like a bug.

Hey everything seems to be working now, just one last question which is confusing me: isn't the objective of this issue to NOT show the Welcome Page when opening a new project? So why is your enum suggestion welcomePageInEmptyWorkbench? What is happening right now after my additions is: upon opening a new project, no Welcome Page is shown. Is this right?
Show it only in the empty workbench. :)
Hey Now I'm getting upon opening a new window (empty workbench). Any ideas? I did the comparison as you said for no folder being open.
Is the ?
