I’ve never been fond of the backend for Vera3. For one I would like a darker background, and the icons and way that the devices are spaced is not compact enough. It’d be nice to have something more responsive. I don’t want to customize my own skin but am hoping there are skins that I can download.
There are no known skins to download for Vera. Consider this project that is being actively worked on. I use it, have a dark theme, and you can customize things you want.
