I have to admit that I had not come across midnight-commander. It certainly looks interesting and I'll be giving it a spin. Thanks for pointing me in its direction!
I do intend to expand nav's feature set to come close to an `ls` replacement, at least for the most common workflows, whereas midnight-commander and other similar tools are perhaps closer to being (or are) file managers. I'm also hopeful that by using the completely awesome Charm [0] libraries that I can make for a pleasing/modern UI. Either way, I had a blast building nav and look forward to continuing on.
Thanks again for the comment!
