Hi! I just make quite a lot of modpacks in the Modrinth launcher and a lot of mods have moved there. It is also possible because the service is developed only for Minecraft. It would be much more convenient if Building Gadgets was also in Modrinth, otherwise I have to download it separately for each modpack and check for its updates, but this is very inconvenient when creating modpacks.

Not at this time, sorry, Potentially in the future. :)
