SP Simple Portfolio is possible without 'View' ?

Ciao,
yes, it's possible / si è possibile.
But you have to use custom CSS to hide this button, if you don't want to touch php file.

Here is universal CSS code for SP Portfolio component: / Ecco il codice CSS universale per il SP Portfolio:

a.btn-view {
    display: none !important;
    visibility: hidden;}

Remember that you have compressed CSS files now, so you have clean CMS cache after adding my code.
