I see that it kind of works, but it still creates a lot of double typing. When you create alias of any type, you hide the original value - like IP in my case (but same goes for ports!). So if you see a log entry of a certain IP and wonder where/what host it is, you can't just hoover over the alias-group to quickly isolate/find the host. Alias is often a good way to help find Host Alias->IP, but the interface ignores the other way, IP->Host alias.
The hoover should contain the alias value as well, like IP, port or whatever the original value is. A work-around is to enter the IP in the alias, but this creates a possible difference in real value vs textual description and a lot of extra work/confusion.
Hope this is fixed in later versions.
Another usefull feature developers could implement, is the number of referenced IP, hosts etc. in the fw rules, from Aliases. This is how Fortigate does it (if an alias is used three times, it has a link with number 3 that leads to fw-rules).
