I'm sure it was added as part of the thumbnail overhaul, but it's welcome. Sure beats trying to figure out which daily challenge entry failed to drag and drop.
Also a good time to remind everyone to use the "Add Post" button above the gallery when possible. It gets the LoRA maker 50 buzz, which is 1/10th the cost of training an SD1.5/SDXL//PDXL/ILXL LoRA or 1/20th of a ZIT LoRA. It's now easier than ever with this new feature since you don't even need to drag/drop onto post anymore.
