Behavior of zooming via mouse wheel

[Alexander Wolf]

Could you make zoom with the mouse wheel at the point where the mouse cursor like in Google Maps?

Short explanation from question: If I want to zoom in on a star that is located in the upper left now before I have to center it on the screen and then zoom in, zoom with google style simply position the mouse cursor and zoom in on the star, it is more
 immediate, more simple.

Note that implementing this will automatically annoy everyone who is OK with/used to the current behaviour. :)

Note also that this will mean that there won't be a way to manipulate "general zoom" with the mouse.

Yes, I know. More info you can get via related question.

Hi, I think that this would be a really good feature. However, I can see why some people ("more professional" I guess?) would prefer the current zoom behavior.

The solution, I think, is to allow both behaviors by allowing to set one's desired zoom behavior, for example: a button in the lower bar (beside "Night mode", "Full screen mode" and so on), with an icon that resembles a magnifying glass with a mouse cursor inside it (when enabled, the zoom is cursor-centered, and when disabled, the zoom is the traditional one).

The only doubt one could have is wheter to default to cursor-centered zoom or traditional zoom: if traditional zoom will be default, accustomed users won't feel the difference (which is good). But, if cursor-centered zoom becomes default, then the Stellarium software will become more user-friendly (after all Google Maps is very user-friendly) thus could potentially be enjoyed more easily by novices/hobbyists/enthusiasts (like me). Sure, professional people should activeli opt-out, but I think that the overall Stellarium experience would benefit from this feature.
