Thanks for this library.
I am new to rust and was playing around with the examples to get started.

Just encountered this warning on compilation

Since this pelletier/go-toml#541 is in v1 now it needs to be supported by v2.

(FYI @Felixoid)

I've recently come to realize that the 'one-size-fits-all' mega-snippets on marzer.github.io/tomlplusplus aren't necessarily useful for everyone, and I should break them up into smaller sub-examples. I'd be totally happy to accept help with this, though that may be wishful thinking!

Most TUI programs have a useful list of categorized keybindings that shows when <?> or shift+/ are pressed to quickly check which-key does X, or see what commands are available to the user. I believe this is a low-input/high-return improvement for all new users. This would also make the project feel much more polished.
