There are still many difficult ideas to be researched, which will spend
a long time, so I decide to make a new release, supporting "plugin

A tip:
To select language manually, make a file named "Option.ini" in the same
folder of the program, and edit it as following:

[Options]

; Language Settings:
; 0 - Auto
; 1 - English
; 2 - Chinese (Simplified)
Language=0
