I would love to see an "Upload clipboard image" function

I am test the current version of Brave after using Slimjet for awhile. One thing I really miss is the ability to upload a clipboard image when adding attachments to forum posts. This function is triggered by an “Upload clipboard image” button that appears in the file browser window triggered by that add attachment function of forums. I have found the ability to take a screensnip, copy it to the clipboard, and then upload in a forum post to be very valuable. It is much easier than saving the image as a file and then having to browse to it to add it. Thanks for this consideration.
