Hello Bloyamind. Thanks for the good words. Hidden doors can be seen in a couple of ways. First, make sure that you don't display secrets by going in the menu Relorded > Map and disabling "Show Hidden/Unopened". And second, make sure your leading member of the party doesn't auto-sense hidden doors. But that door being "seen" should only happen after the party has stepped next to it once. Let me know if these things don't work, that would be a bug.
ONLY THE LEADER USES THEIR SPECIAL ABILITIES.
Now you could play Relorded without sensing anything hidden by just playing like we used to play Deathlord: use humans exclusively. :)
No one ever used any other classes because they sucked compare to humans.
As for F11, I should probably provide the ability to zoom 2x the original window.
