Categories Only view remade into two columns

[Canapin (Coin-coin le Canapin)]

Alternative with flexbox:

.category-list tbody {
    display: flex;
    flex-wrap: wrap;
}
.category-list tbody tr {
    width: 50%;
    display: flex;
}
.category-list tbody .category {
    flex: 1;
}

Still a few tweaks to do though.
