Hi Ivo,
I have a problem with j2 store categories module in Home page: the categories are displayed in a list and not inline (see attachment)
I copy/paste this code in my custom.scss file, but it didn't work.

// My Products Categories



.j2store-categories-module {

    padding-top: 30px

}



.j2store-categories-module li {

    display: inline-block;

    list-style: outside none none;

    padding: 0 20px;

    width: 33%

}



.j2store-categories-module li img {

    height: auto;

    width: 100%;

    max-width: 100%;

    border: 1px solid #eeeeee;

    opacity: 1;

    transition: all 0.3s ease 0s

}



.j2store-categories-module li h4 {

    margin-top: 20px

}



.j2store-categories-module li h4 a {

    transition: all 0.3s ease 0s;

    color: #333333;

    font-weight: 600

}



.j2store-categories-module li h4 a:hover {

    text-decoration: none

}



@media (max-width:768px) {

.j2store-categories-module li {

        width: 100%

    }

}



.j2store-categories-module li:hover img {

    opacity: 1

}



.j2store-categories-module li:hover h4 a {

    color: #25802e

}

Also I have the import "dependencies"; rule in my custom.scss and recompiled the Base Outline of template.
I tried to delete the browser, joomla and gantry cache, with no success. If you use Firebug you'll see that the custom file is not read.
What else can I try??
