great improvement @bernardodemarco , I have one question; by the look of the code this would apply to the normal list view and to the metrics list view, but in QA I only see the extra column in the metrics view:

Is this

• expected vs my expectation,
• something wrong in the qa env or
• should this change be applied in a second location?

tnx

[bernardodemarco]

@DaanHoogland, yes, it should be displayed by default both on the normal list view and on the metrics view. Maybe, could this be related to browser caching?

I accessed the QA environment in a private tab, and this is the default host list view that appears for me:

2025-04-30.08-14-45.mp4

The same behavior also occurs in my local environment.

thanks @bernardodemarco , I am using duckduckgo browser and thought it would not cache anything. I was so wrong 🤦 .
