The closest thing you will get right now is to enable "Scroll To Source", however it will actually open the file in a different tab, it will not be viewed.
Open the Project panel, Favorites, etc. (cmd + 1 or ctrl + 1)
Click the gear in the upper right corner 
Select "Scroll to source"
Note
You can enable โScroll to sourceโ in the same way as โScroll from sourceโ, just make sure you click on one file that you wait until the sidebar reaches another click, otherwise the sidebar will automatically scroll between them. You need to click one of them to break this loop.
