AI Summary: The user is experiencing two issues with RC7 firmware: the battery indicator occasionally disappears after the keyboard wakes from deep sleep, requiring mode switching to reactivate it. Additionally, when toggling between Windows and Mac modes using FN + WIN, the backlight temporarily shuts off in Windows mode, and the color change isn't immediate in either direction, with the user requesting instant color transitions.
