[Rd] Better support ESS by allowing choice of CRAN mirror using the `menu-choice` widget
I know ESS already has a better interface for installing packages, C-c C-e TAB, but it'd be "neat" if when I forget to do this and I call install.packages() without first setting a mirror that either the same interface would be presented rather than Tcl/Tk, or a widget.el-based interface was presented.

You could avoid the issue by setting the CDN-served cloud.r-project.org up as
your default. The ways CDNs work, they will always automatically find you the
closest server in their network. No need to manually select.
I set the following up as the default for the Debian (and hence Ubuntu,
PopOS!, ...) package back in 2018 as part of Rprofile.site:
## We set the cloud mirror, which is 'network-close' to everybody, as
default
local({
r <- getOption("repos")
r["CRAN"] <- "https://cloud.r-project.org"
options(repos = r)
})
and use it personally too.
In your case ESS would dispatch to R, and R would do "The Right Thing
(TM)"
as instructed.
