The main difference from the original chinese version is to making this h5Player more general for every website.
Features are not as many as the original one, but more efficient and effective.
The enhancement won't bring significant performance impact to the usage.
Same as original, the functions are used by shortcut keys.
For the performance, it is still a long way to go.
The following features are unlikely to develop in the near future:
"Fullpage"
"Screen Capture"
To use this script, your browser shall be a "modern" browser - supporting ES6, CSS3, and etc.
