> it should be like and dislike buttons.
actually it is configurable, it can be enabled, but by default it is one-way "Thank you!" or "Like"

> How some 1 gona share the post on their profiles
There is already a button in "Share" block to share content(including posts) in own timeline

> Version update should be in Extension>updates section instead of dashboard
It doesn't matter actually, since updated is performed automatically anyway, you will just see more get notification by email that the site was updated.

> Ocean template is too flashy bright type
There is alternative "Lagoon" template

It's better to discuss it in forums...
