or in ExecTBL.ini on the line that starts with "LSONSKINSTART" replace VISU with GPS
IG will set its day or night mode automaticly, you just have to set it to do so, RR or the Skin can not do this for you. In IG go to Menu button>Settings>Display Options>Day/Night set to auto
Not sure which ig hack your referring to, there are a lot of them. But i still recommend the one that is bundled with the skin (found in the LSTOOLS folder)
It skins all the buttons in IG to match lsxvoid skin (there will be an update to this also).
in the next update the visu will not start automaticly
