Hello again and thank you for addressng the various points. It appears I was under the wrong impression of the scale of the "pro" version. Taking into account the what you listed I can understand it being sold as separate product. It's not just more features and content but an entirely different workflow and possibly targetting a completely different set of users. With that said I'm glad the "legacy" versions will still be supported and possibly received QoL updates that you learn from doing the "pro" version. I know you had a lot of work with the last tilesets but I'm really eager to see what your next character pack will be since those are the hardeste to come by with good quality and hunting assets. Now I don't know if we'll get a regular character pack next or the new creators but I guess I'll have to wait to find out. Keep up the good work. If I remember some extra feedback I'll reply to this (or your reply) to avoid filling up the comment section with this.
Speaking of which, not sure if you still have it but I think when I 1st got the packs I suggested keeping export spritesheet direction order consistent (for easier import workflow) and also, in case you do projectiles again give a version without movement built-in the animation (sprite always centered so people can move it as they wish inside their engines). Not sure if it's still relevant but better safe than sorry.
Thanks for listening and replying and have a good day.
EDIT: As I kept thinking about it, the "pro" version sounds like a massive undertaking if you're going to allow things like creating animations. Maybe you're already aware of this but that sounds not only hard to implement but also hard to expose to the user in a way that is easy to use. If I may make another suggestion, depending on your asset creation workflow and compatibility between the systems, you could maybe sell character packs as "presets" usable out of the box like they are now and the pro-version could include those assets (already build-in or included with the character package, an "extension" file for the creator to support these assests as well). For people that want stuff that just works they have the traditional packs, and the users that want maximum customization can use the pro-version and still benefit from packs coming out by getting extra content for their "pro" creator. Of course this would probably only work characters with the same "shape" so maybe monster or animal characters would only be able to be sold as a standalone packs and not integrated in the creator but hey, if you somehow worked out too the better (but realisitically it might provide some challenges that might not be worth it, at least for the first iterations)
Part of me saying this is because I feel that if the "pro" creator is your next project I don't think we'll see anything for several months, and if you could find a way to make pro creator and packs compatible (maybe only future packs because retrofitting this is probably a lot of work) you could make some character packs from time to time as you work on the creator and you would also give yourself an easier time to drop packs/extensions to the creators content in future without leaving creator buyers out because content only came out on a char pack, or leaving pack buyers out because the new content is only for the creator. With a sort of extension system, packs could be sold and double as stand-alone and pro creator extensions. Priced correctly I think it could be a viable business model. It's extra work for sure, but if you're going to do all these advanced features anyway, maybe consider this.
