Do Button was a Shorten of Apply because the button size was small in V1.0 and i couldn't write Longer Names , and it do nothing except when you write a value it confirms it and removes the focus of the line edit button, and to revert the setting you can press "open data folder" button from settings , then you will find two files in the data folder , one for saved settings and the other for palettes , deleting the palettes file will reset all the palettes to default , and same for settings. last , i don't know what do u mean by in bulk, but if you mean by choosing a number of random characters to generate and export all at once then maybe i could add this later . thank you :)
