Added UntitledMerger to extensions

[silveroxides]

Info

A fast and very functional merger. Not mine originally. I have taken upon me to try and keep it updated and compatible. So it is a fork but original maintainer is unable to continue development due to personal reasons and I thought it was too good of a merger to keep to myself. sd-webui-untitledmerger

hi this is to notify you that we are adding a fork of your extension sd-webui-untitledmerger is added to the index

typically we prefer to add the root repository, but since the extension is currently broken in 1.9 (due to changes in sampler / scheduler), and according to @silveroxides you won't be able to continue development / maintain it (most of communication is done on Discord), we will be adding the fork the the index

if for some reason you would like the extension removed from index please notify us
