I still hope Scribus will even work better with QT5 so there will be no need for another office suite! At last for me.
Scribus is not an office suite I know. But it is much more powerful for an end user if used!
You have to open one! text frame only to get word processor functionality and more.
With Scribus you can create Books!
To write a letter with it should be possible then!
For me it is more important to get the Haiku Beta out! Nice to have package management if it works! If not it will work in the future!
