Allow for either all or part of a dialog tree to be copied from one skill to another. Currently if you have logic implemented in one skill and want to reuse it in another skill you have to completely rebuild it. The ability to copy useful dialog trees, with options to include all of the associated entities and intents, would be immensely valuable and make development a far less painful process.
Even better would be the option to save useful dialog trees in some globally accessible repository, again with the option to include all associated entities and intents. This repository should then be accessible to you from any skill you are building.
One further extension could be to allow these dialog snippets to be shared between other users of Watson Assistant in a community portal of some kind.
