Targeting cursor dot, and spell cast at non-target

I would REALLY like to have an option to toggle a small unobtrusive grey dot cursor center-screen that would "auto-target" actionable items/creatures... and that while in combat mode, would auto-target any enemy or ally while it is over the creature. This would enable play uninterrupted by having to stop and click to target. ALSO, I would REALLY like to be able to cast a fireball, for example, at the ground or near potential targets... regardless of range. I am not asking for unlimited range, only for the ability to cast them untargetedly. Currently, you can only fire at targeted creatures within range. Sometimes it is best to cast area effects in between targets. So far, these two limitations are my only gripes. Maybe the ability to cast these spells "at the ground" would only be enabled in out of certain town areas to keep things from getting too chaotic in towns.
