New Theme - Titan City - Work in progress.
I have a LONG way to go here, but I thought I'd share a couple of things.
A little bit of Lavender and Vanilla in a blender plus feature requirements from in house.
Short version. The front page has a collapsable nested view of the Categories with the assumption that the top parent categories have no topics.
Posts have a severe abuse of the groups behaviour to implement forum titles and badges. Badges are displayed by placing a png file with the same name as the Font Awesome icon assigned to the group in the public/images folder ( ie fa-apple.png. ) If the file is not present the normal Font Awesome icon is not displayed - it doesn't mix and match yet.
Once I get a handle on plugins I'll probably move the badge code into a plugin. I also intend to push gravatars out into a plugin, add a custom SSO module, and add font-custom.
The I get to the prettification.
Oh. A link would be good.
I'll definitely keep that first one in mind - It seems very applicable in mobile, but on my silly-big desktop monitor I would find that it trades that for excess scrolling - I think. Certainly something to experiment with.
And the sidebar seems a very solid thought, I'll have to look at some other themes that have done that...
It had been a bit since I looked at the code for the child categories. The width is based ( at this time ) entirely on the the category's css class. And I've modified VERY few of those at this point - so it's very defaulty.
