That may sound like faint praise, but if you check my dozen odd reviews, non-functioning extensions aren't as rare as you think.
Problem with, to name names, Color Toggle for one, is that the alternate color profile can easily hide GUI links, and actually render them inert [so even if you know where a button is, you're still screwed].
TDC does one narrow job, but does it effectively. Kudos!
