Not sure if this will be an unpopular take but... Obscuring all of the technical detail from people holding private keys -- essentially giving them an "easy button" -- can often result in them feeling less confident about the keys because they don't have any sense of what's going under the hood. Letting them get their hands a little dirty, letting them work with bitcoin primatives (especially ones that are portable between different tools), can help to significantly increase the confidence with which people hold their keys.
