I think it would be great to be able to update the names of files once they’re uploaded; this is especially needed when linking images or files from online instead of uploading since you have no control on the naming structure for those external files. I’ve recently found that searching a base includes what’s in the filename and this is becoming problematic since I often link to images on the web that have a lot of text in the filename that I would prefer not to be there.
I think the ability to edit properties of uploaded files once they’re in the base would be a huge help.
