It would be way better if we were able to shift+click to select a bunch of workspaces/templates to do mass actions on them (especially deletion).

Let's say I've been creating a lot of workspaces to test out my new template and end up with 30+ workspaces, i'll have to select them one by one or select everything and deselect the ones that aren't related.

Most web support this (e.g GMail as a quick example), this is really frustrating as a user.
