Heya!

Just an idea of implementation:

Camera Options -> Focus Target on Free Camera: [on/off]

/focus [on/off]

This would give the player to focus its actions to the target even in free camera mode. In Lock-on mode it's obligatory, so there's no need to modify its behavior.

On a side note, I think that everybody has the right to have some things without a restriction. Anyway, I find it pretty useless, because if I have the camera sticking on the ass of my character (which is a nice view) I could simply zoom out the camera, and being able to see everything in another, very stunning perspective. Darn, you don't know the screenshots I do with the Lock-on technique =D

You like it? You don't? You have a better idea?

See ya!
