Hi thecedarsrc,
The slider width is

	add_image_size( 'slider-narrow', 1038, 460, true ); 		// used on Featured Slider on Homepage Header for narrow layout
	add_image_size( 'slider-wide', 1400, 460, true ); 			// used on Featured Slider on Homepage Header for wide layout

If you add more image size then it automatically cuts off to the new above defined size.

We have no any options to enlarge the text box. To have a simply gallary link then it needs code customisation. The code is inside theme folder -> library -> widgets -> attitude_widgets.php. If you are unable and also need other features too then you need to hire a developer to fix it.
Thank you!
