MBS - Smooth Scroll

First, I am not good at English, it may be hard to understand.
I am sorry about that at the beginning

Thank you for a wonderful plugin!
On the other hand, as you are talking about, there is a problem that the character trembles when scrolling.

I found a description of the plugin command on line 184.

/**
* Comando de plugin
*/
Game_Interpreter.prototype.pluginCommand = function (command, args) {
_GameInterpreter_pluginCommand.call(this, command, args);
if (command == "SmoothScroll") {
if (args[0] == "enable")
$.enabled = true;
else if (args[0] == "disable")
$.enabled = false;

I thought that it would be possible to switch on and off for each scene with the description of "SmoothScroll enable or disable", but it seems that it is not functioning.
Do you know anything about this?

And another one.
Is it possible to modify this plug-in and redistribute it?
There is a wonderful engineer in Japan, and there is a possibility to make this plug-in better.
I am glad if you consider it.
Thank you.

Sorry for the continuous post.
Since the doubt solved, I will share it.

>I found a description of the plugin command on line 184.

I confirmed that it is functioning here.
I thank Mr. Masked for implementing it.

Also confirmed CC BY SA notation in # 1.
It is a wonderful plug-in so I would like to recommend it widely in my country.

Finally, there seems to be a problem that the character coordinates are shifted to the RMMV when the movement speed of the scroll is not an integer.
It does not become obvious in the event command.
It seemed to be occurring in combination with scripts and book plugins.
Thank you.

I edited the text for URL change.

I will excuse consecutive postings.
About the event that the character shakes during map scrolling.
Astral merged the proposed amendments.

Astral said Credits and reports are unnecessary.

I hope it will be resolved here as well.
