There should be a global "Default" button in the theme settings menu and an "OK" button. If the back button is pressed of the OK button, the theme settings will reset to before you opened the theme menu. This will prevent config saving lag every time you change one of the colors and go back. Also, the loading screen should show when saving settings.Morning guys! I've just attached beta 29. This update improves the screenshot code. Screenshots are now rotated in processing so are saved the right way round. Both screens are now drawn in one (larger) image so you don't have two separate files for the screenshot. Also, the screenshot PNG files are given unique filenames so they no longer get overwritten when you take another screenshot.
