Title bar is good alternative.
Adding codes below to Rprofile.site works good.

utils::setWindowTitle(base::getwd())
utils::assignInNamespace("setwd",function(dir){.Internal(setwd(dir));setWindowTitle(base::getwd())},"base")

I agree.
A standard interface is a good interface, and a good interface helps our works.

Thanks, again.
