Propose new functionalities for Decidim software

In my opinion I think it makes sense to act in tree logic:

If I'm interested in level 1, I'm interested in level 1.1, 1.1.1, 1.2, 1.3 ... if I'm interested in level 1.3 I'm not interested in level 1 or the others. It would be the same logic as the newsletter.

It would also be interesting to notify of the version's changes of the result. What do you mean with new step?

@carol Additional info
**Is your feature related to a problem?**
As a user I want to be able to follow a result and receive notification when it's updated.

**Describe the solution you'd like**
Add a follow button on the result page and send notification to user on the following events :
- New comment
- Change in percentage of completion
- New step added

There is one complex thing to handle : how to handle subscription with the parent - child - grand child data structure result have. Example :
- if I suscribe to result that has n childs do I receive notifications aout all childs as well ?
- if I suscribe to a child result do I receive notifications about the parent ?

**Additional context**
Related to this : Notify participants when result execution state is updated, for those results related to their proposals

**Does this issue could impact on users private data ?**
No

Hi @virgile_deville, as @paarals says, what makes more sense is to follow the hierarchy. If you follow a parent's result, you'll get notifications from their children. If you only follow a child result, you don't get notifications from its parent.
