I do like that it's available offline, but does it have live traffic if you're online? Waze has informed me about many a traffic jam and helped me circumvent them. Plus temporary road closures in case of big accidents, etc.
Edit: Ay, it's Estonian! Always cool to see something come out of my tiny home country.
I don't think that is something that it has yet, It's possible that they could be working on something like that though. If you don't find anything, It would be worth a suggestion for sure.
