Feature Description

Would it be possible to add a way to open the files in another tab like Github?

In Github, files can be opened in another tabs by middle-clicking (or CTRL+Left click) on it

Screenshots

I am talking about this view

For example, in the same view in github when I middle-click on attachment.go the file is opened in a new tab
