I’m using LibreOffice Writer and most of the time are also using full justification for paragraphs, so that the Text on the right side as well as on the left side is justified. Because of this there are quite a lot of gaps between words and I am using the manual hyphenation wit “Control-Key and - Key”. The automatic hyphenation is not good enough - at least for the German language in LibreOffice, so I can’t use that.
My feature request: LibreOffice should store all word hyphenations I do manually so the next time I type the word, it inserts an hyphenation to that word automatically. It wold save me (and others) a lot of time, I’m sure.
