How to expand number of tags in backend?

Hello,

I am using a lot of tags. In the frontend all my tags are shown because I increased the number of tags to 100 using this filter (the default number of tags is 48)

add_filter( 'get_the_excerpt', 'remove_dropcap_shortcode', 1);	

		add_filter('widget_tag_cloud_args','set_tag_cloud_sizes');
			function set_tag_cloud_sizes($args) {
			$args['number'] = 100;
			$args['smallest'] = 8;
			$args['largest'] = 16;
			return $args; }

My question now: Where and how can I increase the number of tags which are shown in the backend? At the moment then number is limited to 48.

My current tag cloud is in the footer:

Thank you for support and help.
