Does the trick very well & works flawlessly!
Makes sense, I think, to minimize excess clutter wherever possible—in this case for anyone using node statistics.
So instead of the full words: 'Threads', 'Messages' & 'Views', we simply have a single FA icon replacing each word, which effectively means discarding seventeen unnecessary characters.
Imo, this definitely seems to improve the overall visual presentation.
Thus, I am giving a full rating of 5/5 stars because this is without a doubt yet another top quality add-on by an exceptional developer.
I absolutely recommend both this [cXF] 'Node Stats Icons' add-on -as well as the many other superb add-ons available @customizeXF.com
