There is confusion around the new DB input field, the UX could be improved by making it clearer what should go in the field and showing hints when typing.
- Make the textarea an input field. Add a label before the input.
- Add autocomplete for the DB names
- Populating a [<datalist>](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/datalist) element would provide an autocomplete UI from the browser
