/**
 * @param userId {String}
 * @returns {{label: String, color: String, bgColor: String}}
 */ 
app.proto.cursorPropertiesForUser = function (userId) {
         
    var label = 'intruder'; // :)
    var color = 'rgba(250, 250, 250, .9)';
    var bgColor = 'rgba(200, 0, 0, .9)';
    
    var channel = function (uid, index) {
    
     return uid.charCodeAt(index) + 100;
    };
    
    if (userId) {
    
        // f.e. label = app.model.get('members.' + userId + '.name');
        label = userId.split('-')[0];
        
        var uid = userId.substring(0, 3);
        
        bgColor = 'rgba(' + channel(uid, 0) + ', ' + channel(uid, 1) + ', ' + channel(uid, 2) + ', .9)';
    }
    return {
        label: label,
        color: color,
        bgColor: bgColor
    };
};

To use the component pass it to app.use as usual.

app.use(require('d-textarea-mc'));

Replace your textarea in template:

//textarea {{_page.text}}
d-textarea-mc(data="{{_page.text}}" cursors="{{_page.textCursors}}" userId="{{_session.userId}}")

<!--<textarea>{{_page.text}}</textarea>-->
<view is="d-textarea-mc" data="{{_page.text}}" cursors="{{_page.textCursors}}" userId="{{_session.userId}}"></view>

Collection _page.textCursors must be unique for _page.text.
