There is only one thing I miss from older versions of Microsoft Word (and none from newer versions): In Word, it was possible to add actual styles to a custom menu/toolbar. The customisation dialog included a group of existing styles.
My writing includes a lot of custom styles, and I found that organising my styles as a toolbar of style groups, with each group a drop down menu, made applying the styles much easier.
I don’t think this is possible in LO. Can I make this a feature request?
