@AnvitaPrasad it nice to have this feature but i m not aware how much this will impact @walterbender what do you think ??

[therealharshit]

I don't think switching languages is something people do regularly, so we don't need that level of optimization for it. However, it's still good to add some level of convenience for the user.

@therealharshit I m too thinking of that actually if I choose english as my language it remains constant for a long while untill I try some other language which is not usual let's see the Walter's response on this !!

[walterbender]

We really do not need to add this complexity.
