It would help tremendously if we could simply upload javascript libraries/css instead of having to paste them into the Javascript/css section of the application. Or just being able to add javascript/css elements (as in records in the database) would help out greatly.
ie. could have a simple object with a name (short text) and a long text field and users could have the ability to create multiple objects per app which Knack would load as js or css
Having the ability to separate js/css out from each would make the project cleaner and easier to maintain.
