Options shortcut 'o' doesn't work for cryptocurrency

[miraclx]

After seeing #34 & #37, I think, when you press o to view options for crypto, either a helpful dialog should be shown to the user or at least a note in the Help pane under the Toggle Options Pane section.

Hi again, so what do you think about implementing a pop-up dialog informing users about the unavailability of options for crypto?

I'm not really sure it's necessary. The Toggle block doesn't have the Options 'o' item in it when on a crypto tab, plus you've now added a notice on the help page.

Oh. Just realized the toggle block doesn't include that. All good then.
