Not sure if this is a bug or it's just not a feature, but when I adjust settings in a neural filter, there is no progress bar to let me know if anything is happening. The OK button grays out and turns blue when complete – it may be for a couple minutes, or it may be a few seconds – but I don't know whether my PS is just locked up or if any settings are being applied during that time. It just kind of leaves you hanging for a bit. A progress bar would be nice to have.
