@peter-gamma said in LibreOffice on Ubports phone (survey):
write to the external SD card, which I could pull out of the phone and stick into to PC for editing
You can use SyncThing for this purpose, it works well as long as your phone and PC are on the same LAN.
No cable, no manual step required. No cloud or anything like that, the app on the phone and the PC act as a peer-to-peer node to share data.
Or you can use a USB cable to access your data on your device...
Internal storage is often faster than an SD card and nowadays it is larger and larger.
But I'm a bit off topic, sorry.
LibreOffice was working with Libertine, but as always with Libertine you can be lucky or cursed...
Making it a full blown app is possible based on what was done for Document Viewer, but the app will be huge and the effort required is important.
If you can gather people willing to do it (like the waydroid project) it I think the goal can be achieved.
