Better Open Kattis
In June 2022, the Open Kattis team released an update to the Open Kattis user interface and design. It looks okay, but there are some problems.
The Problem Page
On problem pages, you can no longer view instructions at full-width, and are instead limited to half-width with the other side of the screen containing the submission pane.
This extension fixes that, by adding a button to navigate between the instruction pane and submit pane – both of which are now a more comfortable width.
