If you navigate to https://toolhub.wikimedia.org/tools/xtools-ec/edit, you will see that the fields called <API URL>, <Bug Tracker URL> and <Translate URL> all use the same icon representing a bug.
The task is to change the <API URL> and <Translate URL> icons to something more suitable.
Steps:
- Find the place in the code base where the icons are set
- Go to https://materialdesignicons.com/
- Browse the icons and choose the ones you want. Take note of the icon names
- Prefix the icon names with mdi-, swapping out the old icons with the new ones
