The Problem:
Our mChat was active, but not as fluid as I wanted. New members would sometimes struggle to catch up on conversations if they scrolled back a bit, and for everyone, clicking to see older messages felt clunky. Also, when someone posted a link, it was just text. To see what it was, you had to click away, which often broke the flow of the conversation. These weren't huge problems individually, but they added up to a less-than-ideal real-time experience.
The Solution: mChat Infinite Scroll & Link Preview
I decided to try out two dmzx add-ons for mChat: mChat Infinite Scroll and mChat Link Preview. Both are installed via ACP → Customise → Manage extensions, just like any other phpBB extension. Their settings are under ACP → Extensions.
- mChat Infinite Scroll: This extension changed how older messages load. Before, users had to manually click to load more messages. Now, when a user scrolls to the top of the mChat (or bottom, depending on your mChat's "Newest on top" setting), older messages just appear. It's seamless.
The key setting here is ACP → Extensions → mChat Infinite Scroll → Enable infinite scroll, which I set to Yes. I also tweaked Messages per load to 25 from the default 15, as our members tend to scroll back quite a bit.
What I appreciate about the dmzx version of Infinite Scroll is that it was rewritten to avoid common bugs from other implementations. I've heard stories of chat history auto-loading in rapid bursts or colliding with other page elements, but this version uses IntersectionObserver and specific selectors, so it just works cleanly. - mChat Link Preview: This add-on is fantastic for keeping conversations flowing. When a user posts a URL, a small preview (with a title, description, and sometimes an image) appears directly below the link in the chat. Members can instantly see what the link is about without leaving the chat or even opening a new tab.
The main setting is ACP → Extensions → mChat Link Preview → Enable link preview. I also enabled Display image and Display description to give the richest preview possible. The Maximum preview length is useful to keep things tidy; I set it to 100 characters.
These two seemingly small additions have made a huge difference. Our mChat now feels much more modern and responsive. Scrolling through history is effortless, encouraging members to engage with older parts of the conversation. And the link previews have eliminated that awkward pause where everyone clicks away. Discussions around shared links are now much more fluid and immediate.
It's a prime example of how enhancing the user experience in subtle ways can significantly boost overall engagement.
What small, quality-of-life mChat add-ons have you found to be surprisingly impactful on your board?
