Yes, I use -R and "i" all the time.  -R (together with (setq
dired-isearch-filenames t)) is useful for java projects, which usually
don't have much files, but a lot of nested directories.  "i" is
convenient for navigating when I know the directory structure.

Thanks for mentioning dired-hacks, I didn't know about it.
