(pre-statement: both of these suggestions just came out of me wanting to list more info without having to put it in the description of my posts, this could easily reduce the amount of info a poster has to provide manually in the description if they want to give a more clear step-by-step image creation process)
Firstly going over metadata, considering there's been a few additions to PNG info, I think it's worth revisiting metadata info and to allow more information to be stored in it. Basically, anything that PNG info can pick up on that we currently do not have fields to fill out for:
-Clip skip value
-Version number (this is different for each SD UI, so maybe also allow a field to specify which UI was used?)
Now I do understand that there are older images without these metadata fields avaliable, as looking at my gens from each date, it was really only around July and August that at least A1111 started adding more to the PNG info, but I still feel like these are valuable fields to add, especially now that the model name and VAE name, not just the hashes, are now included in PNG info. Posters could still add these fields to older posts of course, as I'll plan to do so if these are added.
Secondly, I'm wondering if it would be worth creating tags for VAEs? It could be valuable info for anyone who wants to do recreations for research purposes, just like listing the model tag and metadata. If so, how could we go about creating tags for them?
