I'd like to have a second season of the tv series. But have it at a higher quality i.e. better/consistant animation, better songs with melodies unique to each episode, solid storylines maybe with an overarching plot, well written characters that could return for another episode. TV content aimed at younger viewers can be enjoyable when its done right (ex: The Lion Guard). Also have it air on multiple platforms to help reach viewers (I think that was a major reason for its downfall as I know I struggled trying to find it when it was airing).
Of course, there won't be any new content if there isn't enough interest for more, new sequel or tv series. Ratings is also a thing to consider as well as creators won't make more of something unless there is money too be made.
As of now, I think the only way we would get any new content is if we generate the interest for it ourselves and somehow let the studios know 'Hey we want more LBT'. However, doing it this way still doesn't guarantee anything happening.
