I would love an one click upgrade solution which doesn't use git in the background. git works flawlessly most of the time but in case something isn't right, it might take unexperienced users a lot of time to fix it (like me, even though I'm a developer, I never really used git).
To make nodebb more accessible for people with no knowledge of css it would be cool if themes could have options to customize colors or at the very least have a few preset theme colors.
selecting one of the options would change the whole color scheme of the theme, kinda like bootswatches for vanilla but added by theme makers.
vanilla and lavander are both kinda preset up for this with the use of variables.less
if you could add a way to select 1 of X amount of variable files you achieve this idea.
this would allow people to get more and easier mileage out of each theme, and help designers trying to make pay themes
this would be the simplest approach i could think of with maybe the long term goal of greater theme customizing kinda like wordpress http://codex.wordpress.org/Appearance_Customize_Screen
I feel like the chats can get a little crowded or awkward when they have more than just two people in them. It would be nice if chats with more than two people showed the name of the chatroom instead of the names of all participants.
