[Input] Selectors should also be optional (via a chexkbox)

[zeh]

Similarly to #26, selectors should also be optional. This way, we can toggle them on or off, and have optional selectors for things like tune.

The complexity of this solution is that it'll require the switch to be part of the selector too, so it's removed.

Maybe a way to do this is by allowing nesting, where a checkbox can nest any number of inputs inside of it, like a static text and the selector. But that might also imply the opposite, where selectors can nest checkboxes, etc.

We might need a multi-step approach here as the best solution is figured out without overengineering it.

Requirements

• Think more about this solution
• Implement/convert
• Add more command examples
