There's one thing you cannot do in LibreOffice, and would be awesome if you could do it.
You choose a color to some text, you choose the "outline" effect, and the text color then becomes the outline color, while the inside space becomes white...but I would like to choose the color for the inside space as well, and I can't do it! I would like to, let's say, make the text green with a red outline. Can you guys make this improvement?
Assigning a color to the outline is simple, but no method to then set the width of the outline, nor to select a different color to fill the glyph.
Of course trivial to do in the FontWork feature, but limited in options for font selection or to handle inline with other text.
