It would be awesome if it was full screen by default, then the launcher wouldn't even be needed. Making the 1st.qst load normally will be also good, currently no way for playing it, since if I try to load it manually, the "Not a custom quest" error pops up.
Yes, it was really great releasing the engine first, it wouldn't have been good if all of these had been revealed when people already downloaded and wanted to play LI...
EDIT:
Peteo, Xthost is free and quick. You just choose an username, get a password and upload your file.
CastChaos,you can play the first quest by registering your name as usual,then instead of trying to load it as a custom quest just press enter twice and it will load.
