One alternative that might satisfy having a regular sized node and exposing options to users could be an autocomplete like we have in the console. If the user pressed Tab and had a popup list of alternatives, or if there was only one option at this point, for the field to just take that option. Even better if the list could auto-update with any user-made attributes within the file. If that could be used anywhere there was an attribute field on a node then it would make the whole process much more approachable and learnable.
