Is った (く) an "irregular form" or "special case" for the casual past positive? It's on the て grammar page as "irregular," but not here ...

You're right! I've added a note for いく with the positive form.

Excuse me if I'm wrong, but shouldn't the Ichidan Conjugation Steps in the Casual, Past Negative section also have the step 2 " Add なかった to make the negative form.", or are we supposed to just infer that the step two from both the Godan and the Ichidan are the same? I think it'd probably be more clear if something was added there, for a second I was really confused as to how just removing the 'ru' ending would result in it becoming a negative, until I checked out the example and realised it was the same as with step 2 of the godan.

Good observation - it could be vague to some people. I went ahead and put it on both so it is clearer. Thanks!

I fear now you will need to add it to the special cases as well, or else someone might believe くる just becomes こ, instead of こなかった ;)
