Hey @drodio,
Rather than using the built-in (and thus perpetually updated) version of Casper you could upload your own copy of it, specificially a version prior to the new look you mention. You can see Casper’s releases here, and I’m guessing that version 3.1.2 would be the latest before the change you mention (but don’t quote me on that).
If you follow this route you of course won’t get any of the new updates added to Casper either, unless you edit the new theme yourself to incorporate that floating text look.
