You can’t limit the number of link per page, only per term.
You cant also use this hook to replace link by mouseover popup
“mywpglossary_insertion_style” change term display mode use ‘link’, ‘popin’ or ‘tippy_poppin’ ( ‘link’ by default )
tippy popin are based on the js lib Tippy.js and ‘popin’ is a simple css only implementation.
add_filter( 'mywpglossary_insertion_style', function(){ return 'tippy_poppin'; } , 0, 10 );
Try it if you dont like to have to many internal link. But you need to know, long definitions are truncated and have a read more link into it.
All usable hook and filter are in the plugin change log.
Sorry for the lack of clear documentation there is all avalable filters, feel free to ask any question.
