Hi, i made a mockup of what I'd like to see personally. I am no expert, obviously.
1. More focus on the Pokemon. I tend to miss a few rarer Pokemons.
2. Colour coded Names based on rarity.
White/Common
Blue/Rare
Yellow/Ultra Rare
Orange/Legendary
3. Show the Type of the Pokemon
4. Show time of day closer to map to give more context. Time is weird for me as I live in the opposite time-zone.
5. 'Options' can be combined with Account Settings and the drop down next to profile top right.
6. Streamlined top bar.
