Not seeing this default button. Where is it at?for you that do not want their eyes blown out at night with the light theme i turned the dark one back on. you can switch the dark one one by clicking the button that says default theme down by the bottom. There are elements that are broken in the dark theme but its useable.....they screwed the pooch with this one. i am trying to sort it all out but i might jettison the whole thing for a new look. either way there will be two looks a light and dark one. just as there has been for the last year or so.
