CSP - Text Input field too confined to work with

Hi there,

Please can you change the current single line text input field for Content Security Policy (custom) in the AdminCP > Advanced Configuration > Security section to a larger text area field?

Modifying a CSP entry is very difficult (especially when using a tablet!) which makes the current type of form field unsuitable.

An example:

content-security-policy: default-src 'self'; script-src 'self' 'report-sample' disqus.com c.disquscdn.com platform.instagram.com cdnjs.cloudflare.com scotthelme.disqus.com a.disquscdn.com go.disqus.com platform.twitter.com cdn.syndication.twimg.com syndication.twitter.com gist.github.com/ScottHelme/ static.cloudflareinsights.com js.stripe.com https://unpkg.com/@tryghost/; style-src 'self' 'report-sample' 'unsafe-inline' c.disquscdn.com a.disquscdn.com fonts.googleapis.com cdnjs.cloudflare.com platform.twitter.com assets-cdn.github.com github.githubassets.com; img-src 'self' data: www.gravatar.com links.services.disqus.com referrer.disqus.com a.disquscdn.com cdn.syndication.twimg.com syndication.twitter.com pbs.twimg.com platform.twitter.com abs.twimg.com www.google-analytics.com; child-src www.instagram.com twitter.com fusiontables.googleusercontent.com fusiontables.google.com www.google.com disqus.com www.youtube.com syndication.twitter.com platform.twitter.com www.youtube-nocookie.com js.stripe.com https://drive.google.com/file/; connect-src 'self' syndication.twitter.com links.services.disqus.com scotthelme.ghost.io cloudflareinsights.com; font-src 'self' cdnjs.cloudflare.com fonts.gstatic.com fonts.googleapis.com; form-action 'self' syndication.twitter.com; frame-ancestors 'none'; prefetch-src 'self' c.disquscdn.com disqus.com; object-src 'none'; base-uri 'none'; upgrade-insecure-requests; report-uri https://scotthelme.report-uri.com/r/d/csp/enforce; report-to default

Many thanks!
