Every time I paste a picture to a Writer document, I have to switch off wraparound, since the default behaviour for a pasted picture is wraparound. Also I would like to pre-set margins for pasted graphics to 3 mm (all directions, just in case I would like to have a picture side by side with accompanying text. It does not other LibreOffice, if margins are defined but a picture is without wraparound).
The other thing that always worries me that the aspect ratio for a graphic is not fixed by default. I also would like to have it fixed by default after double clicking on a picture in order to adapt its size.
If this is not accessible through one of LibreOffice’s menus: Where are all the defaults set? Is it dee in the source code of all the functions dealing with those dialogues or is it one general profile or settings file or is it some resource defining those menus.
