Also, not being to close dialogs with ESC can be annoying since its so intuitive to do so
I was actually going to add this suggestion to the "UI Wishlist" thread a while back - I also find it annoying not to be able to use ESC in dialogs - but I was thinking that Larian might've actually considered this but intentionally left it out, as there are points in a dialog where you're "not supposed to" (for plot/quest reasons) be able to quick-exit a dialog. But maybe they could just make ESC work whenever the standard "exit dialog" choice is actually available?
