Counts all right, no string customisation options

Easily installable and does count something. Unfortunately, the strings in the widget cannot be translatable or customizable.

Loco Translate finds only four translatable strings including plugin’s homepage “https://visitorplugin.com” and the name of the author “Adam Z”, but strings like “Live visitors” or “Visitors today” are hard-coded, so it cannot be used on multi-language sites.
