I like to suggest a small improvement to the dashboard.
While it clearly states what time range is used for "Total queries over" and "Client activity" (namely "over the last 24h")
this information is missing for the other items/sections on the dashboard.
While one can assume/guess it is also 24h (what it is in default) it would be nice if it would be written there. I suggest to change the wording "Top Permitted Domains" to "Top Permitted Domains over last 24h", etc...
