Hello,

thanks for the plugin!

This is just a suggestion/feature-request. It would be helpfull, if one can see at a glance, how the generated outpout and rendered output/theme/design looks like. This avoids having to install the plugin, if one is searching for an alternative theme for typedoc. Thanks!
