I sometimes cannot hear, I wish I could rewind the playback of tutorial videos, I suggest aa rewind 15-second feature, but I appreciate the site as-is, thanks.
Ah my disability. my IQ goes from 60 to 170 depending on my digestion, I see how now, oops sorry
A site suggestion, Often the fine video tutorial comes after one finishes the problem, perhaps peeking at the answer. Maybe the video explaining things should come first?
