for the record, wt-tree is a reference to the unix command tree, which prints the similar format for directory trees in a file system:

• https://linux.die.net/man/1/tree
• https://en.wikipedia.org/wiki/Tree_(command)

I would lean towards conversions and loading being separate commands, personally, though I don't necessarily have a problem with extending wt-tree to look through directory structures (though you may wish to rework some of the formatting, including potentially looking at a dependency to help such as rich and differentiating style/icons/etc between directories and wt5 internal structures)

yeah, I totally agree it's not right to call everything under wt-tree. I really wish I use wt as an entry point (and then have subcommands), but that isn't a great option for Windows...

I will definitely rework the namespace to make it fit better with the tools.
