After some testing I have 3 things to say:
1) thank you Tomi for a fantastic app,
2) all app related features are working smooth,
3) the only downside is when I try to use the /open command after last game was finished, the game tells me:
"Cannot open a Direct IP game on WormNET"...
...so I assume that the snooper is using a different method of hosting at WN, than the game's engine by default, so there's no info about game being removed after 5 minutes or possibility to reopen it.
Is there some way to change this behavior or it's always like that with snoopers?
