So I'm kinda stuck and I hope someone here can help me. I'm building this Control Panel for a data center, and I'm not very good with that. I want to make it as simplistic as possible, but expandable - since at first it will only contain a few functions but it will continue to grow for a long time.
I'm looking for some ideas, examples.
Edit: I ended up buying an administration theme from themeforest. Thanks everybody for your input!
