We had a task like this task before the infraestructure problem.
Now there is a qt5 plugin (libreoffice-qt5) which has qt5 themed filepicker and print dialog, we need to make libreoffice run with that by default. Now one needs to install libreoffice-qt5 (we should include in seed) and then run libreoffice like this: SAL_USE_VCLPLUGIN=qt5 libreoffice.
Maybe change the env var?
- Look this bug https://bugs.documentfoundation.org/show_bug.cgi?id=123072
- Previously there only existed libreoffice-kde* which uses kio so the add extension checkbox didn't appear.
