Hi @DanShai !

Sorry for late response to this but it has been a busy sporing for all involved. I would like merge this one but there are conflicts now. Would you consider takeing the pull and update the pr? If so that would be great and my response will be much swifter.

Thanks for you efforts.

Hi @knsv !
In the last commit, corrected the linter errors , some semicolons and function parenthesis space stuffs were failing the checks ! now it passes the test and no conflicts :)
