Improve Web GUI for VLAN Memberships

When configuring VLAN Memberships with LAG, it is not clear if I have to define the ports as well. Some switches (GS324, GS724v6) allow me to do it, but when I define "T", it automatically changes to "U" which is definitely wrong for most of the VLANs. That is very confusing and I had some strange, not reproducible behavior at some point when I left them at "U".

According to Lyn from Netgear Support who was very helpful on a weekend, you do not have to define the VLAN Membership of Ports which are LAG members.

My Idea: Mark the ports on that page with the number of the LAG or just "L" and do not let the user change them. Then it's clear for everyone.

P.S. In some Netgear switches, the ports automatically gets the TAG from the LAG. That is somehow inconsistent and adds to the confusion.
