4 column layout and 1 column layout (proposed icons included)

[rmacfadyen]

There already are layout-split, layout-three-columns, layout-sidebar, and layout-sidebar-reverse.

It would be nice to have a icon for a 1 column layout and a 4 column layout .

Here's an adaptation for 4 columns:

<svg width="1em" height="1em" viewBox="0 0 16 16" class="bi bi-layout-four-columns" fill="currentColor" xmlns="http://www.w3.org/2000/svg">
    <path fill-rule="evenodd" d="M14 2H2a1 1 0 0 0-1 1v10a1 1 0 0 0 1 1h12a1 1 0 0 0 1-1V3a1 1 0 0 0-1-1zM2 1a2 2 0 0 0-2 2v10a2 2 0 0 0 2 2h12a2 2 0 0 0 2-2V3a2 2 0 0 0-2-2H2z" />
    <path fill-rule="evenodd" d="M3.5 14V2h1v12H4z" />
    <path fill-rule="evenodd" d="M7.5 14V2h1v12h-1z" />
    <path fill-rule="evenodd" d="M11.5 14V2h1v12h-1z" />
</svg>

And to "complete" the set it would be nice to have a 1 column layout. It is just an empty box, but the box matches the boxes for the other layouts. Here's an adaptation:

<svg width="1.5rem" height="1.5rem" viewBox="0 0 16 16" class="bi bi-layout-one-column" fill="currentColor" xmlns="http://www.w3.org/2000/svg">
    <path fill-rule="evenodd" d="M14 2H2a1 1 0 0 0-1 1v10a1 1 0 0 0 1 1h12a1 1 0 0 0 1-1V3a1 1 0 0 0-1-1zM2 1a2 2 0 0 0-2 2v10a2 2 0 0 0 2 2h12a2 2 0 0 0 2-2V3a2 2 0 0 0-2-2H2z" />
</svg>

It would be nice to have a multi-coloured (dark and light sided) layout-split icon similar to Left and Right as well (from VS Code):

No plans for more layout options just yet.
