the models could be named exactly as their formats are
because when everything is called safetensor format it is not so clear what type it is
so there could be a proposal for a name that could be mandatory for many models to have [LORA][LYCORIS][OTHER] at the beginning
systematic naming of the model to make it clear in the folder
The models are already sorted by this, when you search or are browsing you can filter the models by type. Also it shows a small badge on each model's header image (the thing you see when you search) saying if the model is any of those, checkpoint, etc.
