Why don't I see the "Edit feed" button?

Sometimes it may happen that you don't see the "Edit feed" button from your "Feed" space within your account.

It is often caused by a fact, that you are in "All feeds" view, instead of a single feed view. From all feeds view you cannot edit a single feed, that is why the button is missing. Choose any of listed feeds on the left below "All feeds" and "Edit Feed" button appears next to "+ New Feed" on the right.
