There were 2 main points: inverting all colors (ALL colors, not just black and white) and the possibility to quickly turn it on/off. Concerning the second: "It would be nice if LibreOffice had some kind of "night mode" that when turned on would draw the picture of the opened documents with inverted colors" --> "when turned on" "qpdfview has a hot key that inverts colors for the opened documents, maybe the same could be implemented in LibreOffice?" And concerning the first: the whole point is inverting ALL colors, because no theme is going to account for all colors that can be assigned by the sender of the document manually (<a class="bz_bug_link bz_status_NEW " title="NEW - Better support for DE themes to support Night mode/Inverted colors in the LO GUI" href="show_bug.cgi?id=114147#c5">https://bugs.documentfoundation.org/show_bug.cgi?id=114147#c5</a>).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
