Indian vedic sky culture divides the sky into 27 strips (full list, with western equivalents here: https://goo.gl/2PVi28 ), each approximately 360/27 ~ 13 degrees. This division is critical for several purposes including timing rituals and determining the birth lunar mansion/ nakShatra. As it is, users are forced to enable the ecliptic grid and then imagine parallel grid lines running through asterisms in the set of 27. Example pic: https://i.imgur.com/gRcwqcD.jpg . This is clumsy and inaccurate. So, the vedic indian sky culture should show the required 27 grid lines by default.
