I have to admit, it's a great experience for me to develop and maintain Lush. And I couldn't be happier with the release so far; people do like this theme very much, they come to me with questions, requests, pointing me to bugs etc. It's great to see that they really want to use the theme and helping me to make it even better.
However, there's always the question of the direction the theme should go, which means more functionality. Two things came to my mind, which I want to adress to you, the reader and possible user of the theme.
WordPress Widgets
You probably heard already of it, if not: WordPress widgets is a new approach on customizing the sidebar of a theme. You drag and drop all the stuff you want and leave the things out that you don't like. Honestly, I don't like this plugin very much. But the theme is not for me, it's for you, the user. So, would you like to see support for Widgets?
More builtin support for other plugins
I don't use that much plugins, in fact, I have only two activated. And most of the time, I code the stuff by myself, so I can have the control of it. But this leads also to the fact that I don't have a clue, which plugins are popular, well used and would be nice to be integrated with Lush. Can you?
Before you start listing 12^2 plugins, consider that I will not include every one which you name, only those, which seems to be quite popular.
