We have cleaned up Experimental Options tab of old test options that are awaiting further development or decisions. From now on, this is how experiments will be playtested out. Whenever there is something new being tested, we will put it up there, test it out, collect feedback, and hide it again. This is how it should’ve been done from the start, and we’re fixing that mistake now. Sorry for any inconvience if you were regular user of any of these experiments.
