With the ability to filter (show/hide) images by rating, color label and tag I think it would be great addition to be able to also use that power to filter images, for example by media type (raw, jpeg, video) or being able to add custom filters based on variables (we already can sort with variables) and customise it as deep as we need, even with regular expressions, for hardcore users )
For example being able to show CR2 and ARW files separately, though both of them being RAWs
