One of the most common actions, I find, for an input is to bind the value or modify the binding. It would be really useful to have a dynamic binding permanently visible in the App Structure panel for the value property:
I would have thought this might cause confusion - moving one of the Dynamic Attributes to the (Static) Text Input Properties.
But I see what you mean. It would be great to have more keyboard shortcuts or perhaps right-click context menu options to simplify using the UI and to reduce mousework.
