We live in times where apps have to be not only useful but also smooth and delightful. Times slightly different than a couple years ago where all we had to do was just notifyDataSetChanged() on ListView adapter. Screen just blinked, new data appeared and that’s all.
Today, in a times of RenderThread, MaterialDesign animations and transitions app should show exactly what’s happening. User should see when data from his collection just changed or when something new appeared or/and was removed.
