Show Comment while hovering over a Client/Domain

While on the Dashboard or in the Query Log, it should be possible to hover over a specific client or domain and view any comments associated with it.

For example, when hovering over the client [192.168.178.1] on the Dashboard, it should display the comment (if available) as specified in the Clients tab.
I understand that the Clients tab only lists hardware addresses, but this shouldn't be an issue, since each IP address is already automatically linked to a hardware address in the Network overview.

Similarly, for domains, it should display comments from the Domains tab if a comment has been set there, and/or show the comment associated with the list the domain originates from.

I understand your request, but the data from Clients page is actually used only for Group management functions. This has nothing to do with Tools > Network page.

Not sure if it will be possible/reliable to use this information on the query log page.

Do you mean that the data in the Network tab is unreliable for older client entries due to the reassignment of IP addresses aka the possibility that another device might receive the same IP address? Or is there some technical limitation that prevents accessing the data from Tools > Network while viewing the Query Log?
