Not sure if I am missing something, but it seems to me that Bike needs a Focus indicator. Otherwise, no idea if part of your outline is hidden. Perhaps an elipsis at the end of the focused list, or a change in the disclosure triangle?
As a footnote for anyone who is using Keyboard Maestro:
If you gather all your macros for Bike in one KM group, you can display an icon for that group in the macOS menu bar. (Visible only when Bike is active. Clicking it shows a menu of all your Bike macros)
You can also specify a title for it, by assigning a KM variable name to the text to be used for that title (perhaps a single emoji character)
I’m using or by default (to be unobtrusive against dark or light macOS settings), but when the front document in Bike has a focus row (showing one row and its descendants while hiding all other rows), the lightbulb icon is displayed in the macOS menubar instead.
The switching is automated by one of the Keyboard Maestro macros in my Bike group:
and can be placed in your Bike macro group in Keyboard Maestro, to enable a reminder in the macOS menubar of whether or not your front Bike document is in focus mode.
It was added in the last major update, as I made the feature request to Peter (the Keyboard Maestro developer), and he embraced it. He is one hell of a great guy.
