Greetings.
While BRU is mostly used for bulk renaming (of course) many times I find that manual renaming is needed, so being able to do so in the file list is as simple as hitting F2 like in Windows Explorer et al. However, it's annoying to get a confirm dialog saying that you're going to rename exactly one file (well I guess we know that already) and another dialog saying that one file was renamed successfully. On the other side I like the confirm and result dialogs for bulk renaming as they allow me to check if I've selected the right amount of files and after the renaming, how many files have been affected.
My suggestion is a new option to not show these dialogs on manual renaming. If activated, a dialog should only be shown if there was an error in the renaming.
