Create icon pack for iOS or Android devices. Recommended source image size is 1024x1024 px 72 dp, make sure visible layer is selected. Workflow: source image is flattened, bicubic resize applied for each size, results saved in /output folder in source directory. Best practice: create photoshop Action with script, bind it to some hotkey.

Find out what is item's URL and load it when ready. Oh yeah, and show me a loading screen if it takes more than 1 second for preparation. And call off the fuss if item has changed. Hell yeah, ReactiveCocoa.
self.currentItem = item;
RACSignal *itemChanged = [[RACObserve(self, currentItem) skip:1] take:1];
// prepare item until switched to other item
RACSignal *itemReady = [[item rac_prepareItem] takeUntil:itemChanged];
// show description if preparation takes more than 1 second
[[[[[RACSignal interval:1.] take:1]
takeUntil:itemReady]
