If clicking on "Tools > Send System Info" you're presented with a PHP Warning:
Notice: Undefined index: tab in ...\wp-content\plugins\send-system-info\views\send-system-info.php on line 44
This is because there is no $_GET["tab"] present in the url.
Solution
Define $tab with a ternary operator so there's a fallback.
