Please make deletion reversible!

When I right-click and select Remove All to clear the download list, there's also a Delete Files option that I've always been surprised was there since I had just clicked Remove All and thus obviously didn't want to delete the FILES . . . I was always afraid I'd accidentally click it because you can also think of the LIST being "deleted" and not the videos. Well, today I accidentally clicked it, for about 40 videos and even though I immediately cancelled the next window that popped up, all those videos are now completely gone. Not sent to the trash, but permanently deleted and there is no "undo" option for this. PLEASE make this "delete option" have an obvious warning pop up requiring confirmation before executing because one accidental click without warning eradicated all the videos and now I have to download them all again. So frustrating!
