To be free we need usable data, so for instance instead of strange zipped file formats a spreadsheet (witch should not exists, but that's another story) should save data as *sv/SQLite DB by default, a visual doc should be LaTeX or something similar and so on. The suite should be only a viewer.
And a similar project for Photos, also end-to-end encrypted: https://github.com/ente-io/ente
Is there a reason for "HD" printing vs "regular"?
Sorry, my spreadsheet usage is limited to numbers and letters so "HD" printing sounds superfluous.
I know that the office programs theoretically support this, but I found the flow so terrible to be impractical - no wonder casual users don't use it (all the way to many programmers hating WYSIWYG because they hate the process of manual styling so much).
