I don't know what others think about the change, but I really preferred the old right click keybind, where it opens the whole menu instead of only the save function.
Playing obviously with only one hand, but with the mouse (exception to press ctrl instead to skip when replaying), so it annoys me a bit to go over my whole keyboard just to press ESC instead of right clicking the mouse...
It's just a QoL feature that renpy usually has, because I am not only saving, but using it basically for the whole menu, like it previously was.
(Well, honestly, if you know what to look for you can actually just change the keybind yourself in the .rpy files...)
Edit: or in this case .py files...
Edit: And additionally, renpy usually allows to directly exit from the menu, but currently you have to do it from the main menu...
