Expected result

Ability to influence widths and heights of windows and buttons in the Storybook.

Actual result

When I create the buttons in Storybook I can't choose the appearance, how they will look like height and width. It is also not possible to set the default size of the Storybook window. Then the middle button is unnecessarily dominant. It can be fixed by adding spaces to the button name, but it doesn't look good.
