@normis, sadly what you are suggesting is not as easy to see at a quick glance as per the image attached.
What you are suggesting might work for a handful of clients, but when you might have many more clients (customers) you need a better system to see clients at a glance. Grouping also helps to separate active clients from inactive clients while also help to keep stock on-hand levels in check.
If you do a cursory check of your competitors, I’m sure you’ll find they all have the ability to list the info above. For MikroTik to remove the group function from v4 when it was available previously would seem a backward step, potentially giving your current customers reason to seek product elsewhere.
I think this is why so many want groups returned.
