Small new feature, just for admins : in the checkboxes on the right of the comments, if you shift+click on a box it will also check all the boxes above it, up until the next one with a different status: i.e. you check box of the first comment you want to select, then shift+click the box of the last comment of the set, and all between should also be checked. It works also for unchecking all by shift+clicking the last one of the selection.

It allows to easily select multiples comments to delete/archive.
It will be useful when cleaning is needed. Don't overuse it, though, e.g. for mass-deleting posts of poor unreliable users

I'm not very good with Javascript, hence why there isn't that much on the site It works in Firefox and Edge, so I assume it will work in Chrome and other recent browsers.
