Custom view and controler, Stream entry at custum field change, In relation with field

First of all, this is a great peace of software. I am super excited and testing non stope since days
It's so super intuitiv and structured coded that customizations are quite easy to achieve


So I want to do the follwong but don't know what would be the best way:

1) Add a stream entry if a certain custom field is changed
====================================================
I want to have a message in the stream not for all profil changes but just for certain fields (change of Address,Mail,Phone) with a custom message like "User changed his address to NEW ADDRESS"
I found the option to deactivate the profile changed message in general in the stream but

<blockquote>Q:</blockquote> How could I realize that function? With an App that checks new entries in the DB or with an Custom Field that pushes a message to the stream on the onEdit (onSave?) Trigger? Can you maybe recommend an example?

2) Add a custom view that survives component updates
====================================================
<blockquote>Q:</blockquote> Is it possible to add/push a additional view via in a new theme? I createt my own theme but had to add some customized views to directily to the component code. Understandably I don't want to lose this view/controler everytime I update the EasySocial Component. So I need some automated / semi automated way to copy the files back. What would be the best way to realise that?
A kind of app that copies the files back after the update? Do you have some ideas how to solve that elegant?

3) "In relation with ..." field
=========================
I would like to have a in relation with/family tree functionallity.
I found a forum entrie from May 2014 http://stackideas.com/forums/relationship-status-field
about that. Any news if this might be implemented.
<blockquote>Q:</blockquote> If I have to implement it myself would it be better as a app or a custom field, as I will need a new DB Table for the mapping, which also has to be installed via an app/custom field/plugin?

Thank you a lot for helpfull answers

Kind Regards
