Right now current behaviour is saving settings changes when you exit? but it would be nice to have them saved when you click "ok" on the settings window and closing the window, also something similar for the postprocessing window. I tried this myself but couldn't figure it out. Edit by Abdu: Best to do this for the post processing window too and in general for consistency. Currently, closing the windows applies the settings changes btw so definitely should save the settings changes then too, if someone were to suggest adding canceling then it should have a dedicated button to not introduce arbitrary behavior.
