UI improvement: surface type

[gumida]

After tagging several missing surfaces I've noticed two things that might improve the usability a little bit:

1. When clicking on the surface icon a popup message appears and asks for a type to submit. But this message is only visible halfway so the next step is always to pull up the message box.
   
   Wouldn't it be easier, if the message would pop up completely? It least after clicking on "Paved" the complete collection should present itself without any further user interaction needed, I guess?
   

2. That's say I'm in a neighborhood where a lot of surface tags are missing. Usually all this streets are of the same type (Asphalt for example) but I have to redo all this steps for each road/segment: clicking on the icon, selecting Paved, pull up, selecting Asphalt...)
   Maybe a small "same as last time" button would be helpful? So after clicking on the surface icon I could still select between the surface types but on top of the list would be a shortcut with my last selection?

Won't do. However, what I could do is that the behavior as described happens when you double-tap on a quest. Does that sound good?

Has been proposed already. I prefer making the image selector easier to use (with less scrolling), but I haven't had the time to implement it yet.
