Oh, I see. And Electron is not really making things faster.

Seems ok, but it seems to be a dowgraded version from a commercial product. If there is a good Open Soruce product, I prefer that.

I prefer Only Office (Desktop Version) to Libre Office, because

• it does not look like over 20 year old Office 2003
• it uses docx and xlsx as native format which makes it easier for noobs

I heared Only Office has some Russian connections. Otherwise it still is Open Source.
