@Leonie Addison You aren’t able to rearrange those columns (currently,) however you can remove some of the columns that are showing by clicking on the three-slider icon at the top right and unselecting the columns you don’t want to see. I find this helpful to simplify what I’m looking at and eliminate the need to scroll to the right.

Rearranging the columns would be a great feature request. Click on Help & Feedback in the left hand menu and select ‘Have an idea that will make Karbon even better?’
