[cancaonova-desenvolvimento-ti]

We have added to plugin the feature to handle more than one timeline in an unique site.

Hi @cancaonova-desenvolvimento-ti !

I'd love to merge this pull request, but we'd need to make a few changes first.

1. Could you split it into multiple pull requests per feature/change? It's hard for me to tell what exactly has changed with all the code style and formatting changes made along with the new feature. Each PR should only include the changes associated with a particular issue or feature.
2. You'll have to remove all the copyright statements. I cannot include your code if it's copyright of your company, the plugin is licensed GPLv2.
