Needs some work

I guess targeted my review for developers.
I understand that this is a fairly fresh app, so here are a few things I noticed:
1) really slow on updating, searching the city
2) unresponsive/ slow responsive, when clicking on search and on a little "target" (I think this is supposed to be locator, and it didnt respond at all on my click)
3) crashed when I searched for a city at first
4) I dont remember if it prompted to use my location, but it definitely doesnt. Thats why I had to search for my city
5) would be cool to see drop-down of hints/ suggestions when typing the city
6) adding to favourites is super slow... It took a few minutes to get a verification thing like "add ... to favourites" and it took like 5 minutes to the city to appear in favourites.
7) missing "back" buttons, when I click anywhere from the main weather screen, I get lost because I think there is more than one level further.
8) hard to understand the "weather map". I didnt noticed tabs on top at the beginning. There is no hints on "swipe up/ down to change time"
