Here are my first impressions after trying it:
* In the connection properties, would it be possible to label the two endpoints (e.g. This device and Remote device) ?
* Could you add a dedicated VLAN tab to define VLAN IDs and assign meaningful names to them ?
* In the ports list, could the connected device names use the full available width ? Long names are currently truncated, making them harder to read.
Good jobs 💪
