With your preview you’ll see a sizable black circle fills the out there display width. That’s a get started, nevertheless it’s not quite appropriate – we wish some color in there, and Preferably introducing just a little House on either facet so it doesn’t look so restricted.

Meaning incorporating two new Homes to our check out: a single to retailer the array of possible activities, and a person to indicate whichever a single is at present becoming encouraged.

correct, but it will really trigger compiler faults.
