- huge list of outdooractive mapa > improved. BTW: I don't believe your 4 minutes 

Hi Petr
thanks for answer
bad news after your changes
I'm sure you don't want to watch whole boring clip file - so here is the timeline:
(if you need - i can upload the clip)
00:04 start Locus Store from mapmanager map info (screenshot above)
04:21 after 4 minutes 17 Seconds I see 3 folder now
04:30 tap on Germany folder
05:01 after 31 seconds I see a list of federal states
05:06 tap on "Brandenburg"
05:39 after 33 seconds I see my map "Am Klosterwasser"
05:42 tap on map "Am Klosterwasser"
06:14 after 32 seconds finaly I can purchase the map
In total there were 5 minutes 53 seconds to purchase this example map
(from starting in this way)
previously i have to wait only 4 minutes

Now we (I) have to verify and compare experiences and test results from other users.
slow server, slow server scripts, slow connection on my side, slow connection on your side,...
If I have any news - I will post it here...
- Italy > what you suggest?
without a dirty code?

no perfect idea.
So leave it, keep it in your mind and wait for other reports...
