Wow, I've been wanting to develop a LetsEncrypt plugin for NodeBB for quite some time so if there is one now I will definitely take a look soon @julian julian please develop a LetsEncrypt plugin for NodeBB, it will solve lots of problems. Thanks man.
CSS is http://pastebin.com/n3RjP8g9
JS that just makes the theme dark is http://pastebin.com/Z5eEnVUA (Note: I've not tested this, so it may not work, you may have the issue where it will keep adding the same class after every time you refresh.
In case this is the case, I've attached my code below that I use, remove bits until it works how you want it to.
EDIT: The CSS goes in Custom CSS, the Javascript goes in Custom Header under Appearance Custom HTML & CSS in your ACP.
I'm using Lavender Theme on the latest master branch.
When using my mobile (tested iPhone 5s & 6),
Categories/threads don't always load, it's not a very fast/friendly experience. Most of the time you get stuck on the grey overlay (the loading bit..)
Only recently on the master branch it fixed the problem of not being able to login at all.
ideally could have some more development for mobile
Like that except in a widget, just like you have "active users" widget for each category.
Useful mainly for gaming and such, so you can list different teams on your homepage.
I also found a bug in the current version, you hover over a user in a widget. it pops up "Chas", you then navigate to any other page and go back. The Hover/popup of the user stops working. //lavender theme
