@kyrofa @ogra we support gadgets on classic as such, but they cannot be added after the fact, you need your own full image with model and everything (also there is no generally available tooling to make one those ATM, it is manual)

AIUI, the work for dynamic slots (part of what is needed for this) is now towards the top of roadmap list. I’m not working on this (though I suspect I’ll be asked to review 
) and don’t think it is in 2.33. But perhaps within the next couple releases after that (@niemeyer and/or @mvo could comment on the exact timelines).
