Hi mgroenw,
Thanks for trying out Local Like And Share!
At the moment, there is not an easy way to change out the icons.
If you are comfortable with CSS as well as familiar with how the Font Awesome icon set works, you could export a new Font Awesome icon set, with the ones you want to use (saving them to the ../plugins/local-like-and-share/public/font directory), and then change the lines 49-53, as well as lines 102 and 103 in …/plugins/local-like-and-share/public/css/local-like-and-share-public.css (you’d also need to minify this file since the plugin uses the minified file [the “regular” one is provided strictly for human readability]) to use your new icon(s).
I will say, however, that I’ve received a couple of requests for this sort of functionality and it is something I am considering for a future version.
Thanks,
Devon
