I like that it comes in a can, not a plastic bottle simply because it gets colder faster and stays colder longer.
If it feels colder in your hand, it means the opposite of what you assume: It absorbs heat from your hand faster, so the stays colder shorter.
Imagine instead you hold a perfectly insulated container. You could not feel wether the inside is hot or cold, or else the insulation would be faulty.
So if you really want to have a drink that stays colder longer, grab something which does not give away how cold it is, quite literally.
An (intuitively) working search would be a great step ahead. It should find and show things if they exist, and only show no results if they do not. That a plethora of external tools exist to meet these basic needs shows both how much this is needed, and how much it is broken.
I also feel I have more luck finding communities if searching for 'all', instead of 'communities'. Don't make me add cryptic chars to my search to make it work. Do that for me in the background if necessary.
It's been long since I've been using it, but iirc, it's impossible or painful to search for a specific community in your subscribed list.
