The hint addon lets you set up standard autocompletion systems. However we're using it (among other things) to provide a UI for selecting what import to include for a given token. The UX is that you press a shortcut when you're on the token, and it drops down a hint-list where you can select what import to add.
All well and good. But we'd like to add the ability to filter this list down. So we'd like to be able to type and have the entered text filter the list of candidates, but not show up in the editor. So far it doesn't look like this sort of thing is supported. Am I missing something?
