I've donated other developers in the past to create this exact same widget and each one does not even look like the default threads list when in mobile view. I donated to @lms to do this, he attempted to do this several times but due to outside factors he was unable to finish it. His widget functions the way it should except for the fact that it during responsive mobile view, it does not collapse the thread list block in the same manner of Xenforo's thread list or even in the same manner as xfrocks widget.
I asked @Daniel Hood to create one as well but his version doesn't look nowhere near the same as the Xenforo default thread list and he's too busy with his own Reviews project to work on it. As far as I know, only the threads list widget in @Jaxel XenPorta imitates the default Xenforo threads listing in both regular and mobile view properly. This is great, especially considering that it's a free addon. What isn't great is that I would have to install Xenporta just to use one widget and that ain't cool.
I am using lms widget for now. I've spent hours trying to get it to work the same way as the default thread listing but I don't have skills like that.
