- Did not write unit test, because I'am not good at CPP and QT...
- i18n not supported, because i don't know how to contribute. Maybe I should learn how to do this...
By the way
I'm a newbie of C/CPP and QT. I found the konsole does not have this feature, so I just copy/paste and modify some code from the source code. So if there's something wrong with this feature, please just correct it, thank you very much!
