Event Custom Fields

Hi!

I tried to use the fields. Have questions:
1) Do fields.xml file is updated after the update component?
2) Are there any flexible tool to display more information? We have a lot of events in the different blocks of information. It would be convenient to introduce it in the admin panel and units with a wysiwyg-editors, and then specify where they should be in the template file.

Hello

1. No, the modified fields.xml file will be kept

2. Unfortunately, we don't have a tool like that available
