Close but no cigar

I need to :

Edit already set shortcuts. I cannot see the icon result.

Zoom out of icons in case you link some that are too large.

Customize search-bar. So when I hit enter I go to the search results page.

Change notification sources to something else. I just don't use any calendars that aren't my work calendar.

On another note. I absolutely love how clean it is. I wish others followed your example.
