It's unfortunate how Instagram, as a very popular social network, has a very slow speed of improvement. Too many features missing, UI still has issues (not to mention the lack of a dark theme), the UX is just "weird" and the setting menu reminds me of Winphone settings: too cluttered, many useless buttons, and no icons!
On top of that, many times images won't just load. And Videos play automatically, consuming much internet traffic.
