Great job on the Seven theme so far.
I few suggested changes in this patch;
- Accordion styled similarly to Seven's vertical tabs. Also styled to look more "cohesive", i.e. more like one distinct widget as opposed to several separate collapsed widgets
- Tabs styled with a background color for the header in keeping with other Seven styling
- Slider selected state color and border more in keeping with Seven select color conventions
- Messages/Alerts icon removed (in light of Mark Boulton's talk). Also elements given consistent padding
You can see the changes here.
I posted this on the original issue cue (even though it has automatically been closed) because I was not familiar with the process. Apologies!
