Feel free to PR in the full one. We used a custom build to save on space but since we removed it from nodebb.min.js and introduced that loader method I think it's okay to include all of it
And if you can PR this into our docs that would be great as well 
What is your nodejs/npm version? Does it still happen if you remove the node_modules folder and run npm i again?
Use action:composer.submit and the necessary server side hooks. For example filter:topic.create
@shard I think we use a custom build of jquery ui which doesn't have all the ui widgets. Does others work? For example .draggable?
This plugin shows who is currently viewing a topic. This was a core feature that we removed a while ago, now it is back as a plugin 
npm install nodebb-plugin-browsing-users

Notes
Currently only persona supports this, if you want to add it to your custom theme make these changes.
XRegExp should be "xregexp": "3.2.0",
Try npm r xregexp and then npm i xregexp@3.2.0
That's weird, try running npm i and then trying again. Maybe check to make sure XRegExp is installed by npm ls xregexp
i am wondering about that plugin or theme version
You need to load it first.
app.loadJQueryUI(function () {
$( "#accordion" ).accordion();
});
The code @yariplus posted will get rid of the warning. If you somehow have 2 different plugins listening to the same widget hook you should set the html object on the data itself like so.
// filter:widget.render:widget
exports.renderWidget = function (data, next) {
data.html = "<b>Awesome Widget</b>";
next(null, data);
}
