If i have a game let's say, when the character stays and I want him to look like it's breathing, this property should be inside the class? or outside, letting me choose when to breathe, how much, how long, how fast,etc. It's just an example.

did you ever find a way of visually removing controls

ControlDict = this.Controls.FindAll();

Control theButton = ControlDict["button1"];

theButton.BackColor = Color.FromArgb(255, 230, 0);

theButton.Location = new Point(0, 0);

theButton.Hide();

// in practice I'd wrap this in a try/catch for safety, and handle any errors
ControlDict.Remove(theButton.Text);

theButton.Parent.Controls.Remove(theButton);
