This is a big one for me. AN APPEAL: Does know here know of a FOSS that offers an equivalent "experience" (visual appeal, time latency) to Google Docs and Google Sheets? Pretty please?
To explain, I have tried NextCloud-based Collabora and OnlyOffice. Neither comes close to the Google Docs & Sheets "real-timeness" and "visual acceptability".
To explain, this is less a rant and more an explanation, so bear that in mind please: For FOSS like Collabora and OnlyOffice, when "actually used" with the intention of replacing "Google Docs and Google Sheets", both
(1) the literal edit-lag (click, type, enter, wait, see screen update) and also
(2) the looks-bad (ugly dark rectangles, fonts, etc.)
are showstoppers, especially when combined.
There are things the FOSS software tries, to work around these issues best as possible. For example, one mode "runs" the doc on the server and hence sends changes to cloud first, hence the lag, while another mode save changes locally since it "runs" in the browser, but then isn't as real-time (if at all) for "other users" . And neither of these issues addresses the simple visual-appearance issues (painting a spreadsheet that doesn't hurt one's eyes).
If there is a FOSS Google Docs & Sheets replacement that is "good enough", the above description in mind, please, pray tell. It need not be feature-complete. Just replicating a Word and Excel '97 type of usability, but self-hostable FOSS with "real-time collaboration that is rather seamless, i.e. not noticeably bad an any way that interferes with actually using it", would be a most amazing find, IMO.
Thanks.
