[libreoffice-design] Re: Improving comments support

Hi Pranav,

I doubt that we can modify the format- those changes are handled by OASIS 
(http://opendocumentformat.org/, https://www.oasis-open.org/). But there are more experience people 
around, and maybe your idea is being discussed as a future enhancement.

From the UX and RE point of view we have a large number of tickets regarding comments in Writer 
(meta is tdf#106179). Users requests or have trouble with 

* direct formatting (61242,62150,81458,89741,90401,102950,106149)
  and styles (103064)
* threads and long comments (64181,91519,95759,106227)
* insert comments for objects (60976,86387)
* issues with the reference (64731,81018)
* search for/in comments (96474,101936)
* placement (86188, 97487)
* look and feel (38295,95329, 95759,97341,101714)
* accessibility (102950,106180)
* confusion with track changes (90725)

This list is likely not complete, and all the bugs are not listed. But a solution could start with 
a separate deck for comments (tdf#106316). It would support a11y, allow normal threads in a tree, 
supports quick access (which should be the fact today but the Navigator has serious limitations), 
and could offer more interactions.

So far as a quick, though late (sorry) reply. If you want support by the design team we could make 
a proposal of a future UI. Don't hesitate to ask.

Cheers,
Heiko
