why add mouse?

What's the point in having to add the mouse object? I find it really annoying, especially as there is no mouse object visible on the frame afterwards.

Can't it just be there to begin with?

If it's for people who woun't use mouse support in their game i doubt the mouse object is very big.

Yet it will use some space XD, for me everything should be manually added to the game.

Well the design of Construct is aimed that nothing is built in, and anything you don't use isn't included. I guess if it bothers you, you could make a template with the mouse & keyboard (or any other objects you want) pre-inserted. Templates are .caps renamed to .cst with a corresponding .bmp file in the templates directory.

okay, good point.
