The 'Reset All' button [1] is working pretty well now following Patrick L.'s work on bug 156855 [2]. And with os/DE color mode toggle it will fully revert to 'Automatic' values of the default 'Automatic' theme. Improved response to os/DE delivered color values. But still requiring a LO restart. But really only functional at present with the 'Automatic' appearance theme. Unfortunately, when any of the current extension Appearance themes installed via .oxt are active, the 'Reset All' button badly corrupts them--with no means short of manual removal [3] and reinstall to restore them. Need to either figure some way to link the 'Reset All' button to reread/restore the installed appearance theme, or possibly to block its action on themes other than the default 'Automatic' (at least until the Appearance themes can be brought fully into Extension manager control bug 164452).
