the listeners column which is displayed for the listeners name it's not large enough to display the name if they're too long. So the names are cut and it's not very readable. Maybe some columns like Last Access, Requests, Errors, Actions (which are even too long for the content it's displayed there) could be reduced.
Even a tooltip could help,
Additional hint: instead of the listener id in the column Node, the name would help more (or even having a link to the node instance where the actual node name is displayed)
