Collabora Online Weekly Meeting #4

COOL Weekly Meeting #4 has taken place on Thursday, December 03, 2020 at 11:00:00 am (UTC) with participants both from the community contributors and the Collabora team. We have got a quick update on what’s going on and discussed matters raised by the contributors, as well as having the chance to say hi to fellow members of the community. Topics discussed in the meeting include:

  • During the quick update part by Muhammet Kara, it’s been reported that COOL has got 41 new contributors (20+ code contributors) since the move to GitHub.
  • Toolbar changes (by Andreas Kainz) now has a new issue opened for UI changes which is waiting for review from Pedro Silva. Then new pieces of change will be pushed to master based on feedback.

    Ellipsis button proposed to provide a way of opening related dialogs directly from toolbars
  • Contextual toolbars (by Andreas Kainz) also got a new issue for communication and tracking the progress. It has been reported that JavaScript file looks more complicated than the file for the menu bar, and it is proposed to be chopped into smaller pieces to reduce complexity.
  • On the topic of Dynamic Changes of Toolbar Type (by Gabriel Masei), the results of the initial experimentation has been shared, and further options such as making use of a per-user option on the core side for toolbar preference have been discussed. Gabriel Masei will continue working on the topic with the help of Szymon Szymon Kłos, and discussing certain options with Jan Holesovsky. Miklos Vajna has also shared a nice blog post on effective code review and backporting for Collabora Online.
  • Gökay Şatır shared an update on his work of CanvasTileLayer which means a better look with crisp pixels at every zoom level. It’s been reported that Writer and Impress are the latest winners who got some improvements on this. It will also be backported to the 6.4.x series.
  • Pedro Silva and Andreas Kainz shared updates and discussed the next steps regarding the CSS class names step of the icon theming topic. It’s been decided that details will be discussed on a separate call involving the related parties.
  • It’s been reported that Impress got some recent speedup improvements by Mert Tümer (Impress tile rendering and watermarks) and Tomaž Vajngerl (PDF rendering).
  • Szymon Kłos has shared updates on his work around auto-filters and pivot table dialogs, which are still work in progress.
  • Andreas Kainz proposed a coherent approach to maintain user interfaces of COOL, and it has been discussed from different angles. Details of the discussion can be found in the minutes of the meeting.
  • Nicolas Christener shared an update on his work to prepare a blog post about the iOS app upgrade and provided a link to preview the draft.
  • It’s been mentioned that now everything -PC, Online, mobile, etc.- are all on the same 6.4.x base, which makes it easier to coherently maintain all for the developers, and easier to follow for the deployers and the users alike.

Check out the meeting minutes for the details of the meeting, make your own suggestions for the next meeting, and join us on Thursday, December 10, 2020, at 11:00 am (UTC) to stay in touch with the rest of the community. We’re looking forward to hearing from you live. 😉
