Some users complaining about "Topic similar to" window

This can be done quite easily.

You can look at this component’s code and adapt it to hide elements with CSS (target .similar-topics) in users’ preferences settings. That’s exactly what I’ve done on https://unicyclist.com/, where users have a setting to hide the donation icon in the top right of the header.

Basically, the only change I made to the original plugin is that I store the setting in a cookie (I want to remind my user to donate each year for the servers’ fees).

Here’s my own theme component code:

<script type="text/discourse-plugin" version="0.8">
    // set the cookie duration to 1 year
    function setHideDonationCookie(value=null) {
        var now = new Date();
        var time = now.getTime();
        var expireTime = time + 1000*60*60*24*365;
        now.setTime(expireTime);
        document.cookie = 'donationButton=' + value + ';expires='+now.toUTCString()+';path=/';
    }
    // return the cookie value
    function getCookie(name) {
        var dc = document.cookie;
        var prefix = name + "=";
        var begin = dc.indexOf("; " + prefix);
        if (begin == -1) {
            begin = dc.indexOf(prefix);
            if (begin != 0) return null;
        }
        else
        {
            begin += 2;
            var end = document.cookie.indexOf(";", begin);
            if (end == -1) {
            end = dc.length;
            }
        }
        return decodeURI(dc.substring(begin + prefix.length, end));
    } 

function getToggleDonationIcon() {
  let pref = getCookie('donationButton');

  let result = settings.default_enabled;
  if (pref !== null) {
    result = pref === "true";
  }
  return result;
}

// We add the CSS rule in the HTML code
if (getToggleDonationIcon()) {
  let style = document.createElement('style');
  style.innerHTML = ".header-icon-help-fund-servers-fees{ display: none; }";
  document.head.appendChild(style);
}

// technically we only want to amend current user here
api.modifyClass("model:user", {
  toggleDonationIcon: function() {
    return getToggleDonationIcon();
  }.property()
});

api.modifyClass("controller:preferences/interface", {
  actions: {
    save() {
      this._super();
      // set the cookie value as the setting value
      if(this.get("model.toggleDonationIcon") != getToggleDonationIcon()) {
        setHideDonationCookie(this.get("model.toggleDonationIcon").toString());
        if(this.get("model.toggleDonationIcon") == false) {
            document.getElementsByClassName("header-icon-help-fund-servers-fees")[0].style.display = "";
        }
        else {
            document.getElementsByClassName("header-icon-help-fund-servers-fees")[0].style.display = "none";
        }
      }
    }
  }
});
</script>

<script type='text/x-handlebars' data-template-name='/connectors/user-preferences-interface/add-selector'>
  {{preference-checkbox labelKey=(theme-prefix 'donation_icon_toggle') checked=model.toggleDonationIcon}} 
</script>
