It is currently possible to Ctrl+Click to select extensions in version 15. However, it is not possible to Shift-Click to select multiple extensions for editing at the same time. Using Ctrl-Click to edit hundreds of extensions at once can be extremely tedious and time-consuming, and frustrating if one extension is missed while clicking. Shift-Click was possible in version 14, I'm asking that it be brought back as a feature in version 15. I would also like a reason why it was taken out of version 15.
