Welcome addition, but ill just say, all the requests are made in async, so the order of anime will be different for each run. making -S useless for predicting the index

It's the same code I copied from a few lines down.. I didn't think too hard about the logic of it.. and I'm not great at writing sh script, I just figured it was "normal" for sh. Why wasn't this written in bash anyway? It could be a little better looking that way..

@FireEgl cause of POSIX compliance, bash has extra features that are not in POSIX standard.

Is this always the case? If so, I'd like to deprecate that feature

-S ? . It is quite consistent for the search feature unless allanime itself modifies the names(one piece,black cloverrenaming to avoid copyrights). For history though, it is pretty much random

[port19x]

Then -S won't get deprecated, nice

I just stared at these merge conflicts for like 20 minutes and am gonna cut my losses here. This, at it's current state, is irreconcilable with the prior PR. Please adapt and resubmit
