in a video player GUI when trying to hit the fullscreen button i instead by accident click toward the end of the video length revealing a big spoiler in the content.
so i will be more careful. i am so grateful that this is possible; that i can make such a mistake and the software does exactly the command i issued quicker than i could realize and correct it. it didn't try to sell me "spoilerproof shareware" or whatever. it didn't judge me for my error. it simply worked correctly.
#foss forever!
