By azimutz, Removing this info from DEBUG's realm. This will be enabled by default until i gather enough feedback to decide whether it will stay On or Off by default. This info display, is only available on Gui; ShowInfo=No disables it. For the Gui minimalist, "Boot Banner"=No also disables it. Ok, "house cleaning" is suspended until i figure out what Meklort's cooking over at that new branch... "rewrite" :-o just the name sounds scary :-D
