Just a heads up, I'm thinking of a way to define "widgets" for plugins (yours would definitely be a widget type plugin). Then in the ACP you'd be able to customize where it'd show up (home page near motd or as a sidebar, category sidebar etc)
As for putting this on our homepage, I think once this theme is ready it would look pretty good as a sidebar option: https://github.com/psychobunny/nodebb-theme-lavender
Awesome, keep me updated on the widgets thing. As of right now my plugin would still place the shoutbox on the top of the page on that theme.
It is a bit different from the navigation features that are on top, because it actually changes the layout of the site.
There is already pagination customization feature in the use profile. I think that is perhaps a better place for it.
Having a shortcut like that on the home page seem pretty nifty, but right now it is very hard to discover. If we group a few features in the widget on the bottom right and made it a bit more discoverable, that could also work well.
But I would recommend against putting anything like that in the nav bar on top.
