I'd also love a TUI. In the meantime, I wrote this quick bash script that works with FZF for listing and opening content. Here's what it looks like:
I'm probably not able to properly implement a full TUI, but I wonder if you'd be open to at least adding a contrib/ directory where community contributions like this could go? There are probably bugs with this script, plus it relies on FZF, whereas some users might prefer another finder. Having the script inside a repo would let us collectively address those issues.
