I have installed this app on https://98trends.com and found it very useful to manage page links. It did lack my need to just put nofollow links to offsite links which drains your site's domain authority.
Functionality and options seems great. I've been waiting for some weeks to see results. I'm confident it will come, it's just depending on Google's crawl frequency.
Great App great support. Good documentation. Doe just what is says.
