Rodrigo told me about some ideas coming up for the control center (which is using libslab);
* No big sidebar on the control center?
* Few choices visible at one time
* Use the same padding as Nautilus
The first three should be very doable and not require all that much work (although not sure what the "arrow back" means)
The "Few Choices" and "Use same padding as Nautilus" probably goes hand in hand. The issue at the moment is that Slab is designed to work with one icon size, so the padding (ie. space between the items) are hard coded.
I've already raised this issue with the developers as I want to be able to have a configurable icon size.
More talk is needed with all parties to see what they want to do, but it feels like something fun to do in between measuring performance!
