How can I make this plug-in ignore only Chinese characters?

[lizhongliang]

I'm a Chinese who uses English a lot at work, so the text I view and edit often contains both Chinese and English characters.

• I know this plug-in can't spell check Chinese characters and that's OK for me.
• What bothers me is: When spell check is on and whenever my text contains both Chinese and English characters, all Chinese characters are underlined in red, which is distracting.
• I know I can click the "ABC" button in the toolbar to turn off spell check to get rid of all those red lines. But, after this, my English text won't be spell checked.
• I'm tired of having to turn spell check on and off repeatedly. Sometimes, I even forget to turn spell check back on and end up typing text containing typos unwillingly.

So, is there a way to make this plug-in ignore only Chinese characters, or check only English text without turning it off? I already checked the Advanced settings tab of this plug-in and couldn't find out how.
If there's no way to do this, could your team add a feature for this purpose?

Thank you so much.
