Question [Q] lg g2 stock app and cyanogen

hello !

I want to flash cyanogenmod rom (the one based on kitkat) on my phone, but I have some question...

- Will I still have quickmemo ?
- Will I still have knock code ? (knock CODE, not knock on)
- Will I still have quickremote ?
- Is cyanogen stable ? is it recomended ?

which version do I need to flash ? (i have d802 international).

Thanks guys
