Theme switcher button is unclear.

The weather icon for changing theme is a little unclear. I think using the object-inverse icon would make more sense. I've seen other projects use it for this purpose in the past. If you need the icon to be symbolic I just added a symbolic version to the elemenatry icon set but it's not available yet.

I agree, it's a lot clearer as to what the button does
