Great Libary

Wow! I think of the new library samples, this is awesome work that will be used over and over! Yet, TradingView doesn't even have you listed as a PineScript Wizard?? Hopefully they catch wind of this and correct that with the respect you are greatly deserving! Unless, ya know, you just don't want to be named, but even then, I think something should be mentioned, about, ya know, the wizard that created this library.

Thanks for the hard work to make everyone else's work easier! Hopefully you will at least feel appreciated enough to continue to bless us with amazing things!

Awesome work. Congrats. I have a suggestion for the next release. Add vidya, wwma, zlema and tsf in customseries types. Implementation can be found in Optimized Trend Tracker by @KivancOzbilgic. They are useful average functions but they can be reusable too via a general purpose library like this.

Also, I think it is a best practice to put non-defaulted arguments first so I can write enhanced_ta.ma(10) instead of enhanced_ta.ma(length=10). Is that right?

@jason5480, yeah. probably good idea. Will see if I can do these updates in next version when I can. Thanks for the feedback.

One other favor to ask for your next release... :D Please add str.lower in your switch statements to make the string types case invariant! Sorry my OCD is killing me. Thank you again for open-sorcer-ing your magic!

Hello @HeWhoMustNotBeNamed Is it possible to add DEMA in your custom series? Thank you!

@jason5480, will check.
