I've been having this problem for a while, so when I play Minecraft in fullscreen mode ninjabrain bot can't show up on top. Is there any way to fix this? ( fullscreen is like a must for me cuz it make the game so much faster)

Unfullscreen, check ninbot, fullscreen. Or play in borderless and make sure the “always on top” setting in ninbot is selected. Also I recommend joining the discord if u have questions like these. You can ask in #public-help channel
