Collaborans on the LibreOffice & openSUSE Shared Conference

The LibreOffice Conference 2020, this year also known as oSLO 2020, took place from 15 to 17 October 2020 as a joint online event with openSUSE. During the conference, members of the Collabora team contributed with talks on various topics including Collabora Office, Collabora Online, and the Mobile apps. Most of them are available as slides and video recordings. Check out the related blog post for more info. ;)

Collabora Online (COOL)

  • Thanks to Tamás Zolnai for making sure form fields are now properly activated while multiple users are collaboratively working on a document, and also for mentoring other contributors while writing new cypress tests.
  • Thanks to Szymon Kłos for improving UX on Calc documents by removing the intrusive tooltips from the formula bar, making it easier to work with frozen cells and split panes by fixing an issue which caused some cells not being properly shown in such cases, and ensuring that pasting color values to color picker works properly on Impress documents.
  • Thanks to Gökay Şatır for making hyperlink features available in context menus of Calc, Impress, and Draw documents, and assuring quality of the Copy Hyperlink Location feature through extensive testing.
  • Thanks to Pedro Silva for continuing to make COOL more beautiful and visually consistent, by disableing outline on non-form elements, fixing long strings on message dialogs in mobile views, and restricting mobile-related css rules to work only on mobile views, thus reducing css pollution.
  • Thanks to Pranam Lashkari for improving UX on mobile view by correcting the alignment of checkboxes on message dialogs, and adding the missing useCanvasLayer method, thus fixing the build on master which was accidentally broken by a backport.
  • Thanks to Nnamani Ezinne Martina for adding more cypress tests to ensure the quality of Collabora Online on various toolbar items such as Font Color, Highlight Color, Insert Table, Insert Image and Insert Hyperlink.
