Hi!
I’ve been using dmulcahey’s zha-network-card since I started using Home Assistant with Zigbee and I always missed a few things, like being able to filter rows, seeing info about neighbors of each node, being able to add more columns, exporting to CSV and a few other things. So I decided to enhance the card and created the zha-network-card-ext. It’s probable that I will add more features in the future. As any other Home Assistant owner, I’m never fully happy with my setup 
You can install it like you did with zha-network-card (check the README) and you can use it almost like you did with zha-network-card.
If you try it, any feedback is welcome and if you want more features let me know, I might give it a try.
