Homebrew [Semi-Request] DSLibris Moonshell2

[twiztidsinz]

I was wondering if anyone has made (doubtful) or could make a version of DSLibris that supports Moonshell2's extlink so you can open ebooks in DSLibris by the file.
All the tools are available, so hopefully it won't be too much work/effort to do.

I would do this myself, but I'm not sure what to do... so if anyone wants to explain what to do, I could give it a shot.

Anyone?

I hate the way DSLibris lists books alphabetically by book title alone, and not by filename, so series are out of order and not grouped.

 

[jurassicplayer]

I would if someone could teach me how it works exactly xD. We need more extlinks for moonshell.
If only coding came to me like water -_-"...

 

[Xenon++]

So we have to know how to select book works. Then we can override there with that... possibly quoting yslaunch.
But though I had a look, I could not find it. Possibly because there are two opening method for resuming reading.
