With the templates getting more and more sub-templates ( now even the offical ones ) the configuration > hosts list is getting more and more crowded.

To start with it would be great to at least hide the "Templates" column so that not every host item is taking so much screen space:

Bonus benefit would be then, that the other columns are getting more space then.

Idealy it would be great to find a way to manage all columns over an selector.
