This plugin has been deprecated now that this functionality exists in core

https://github.com/NodeBB/nodebb-theme-persona/commit/2b619db7466c2dd1e61f3fbd2f2e5afc56a2bd7e https://github.com/NodeBB/nodebb-theme-lavender/commit/c1821bb2d8493b9377c2750927ead21798b0eff6

Use isSection in your custom theme to emulate this behavior as well. This option is available now by default in core in ACP -> Manage -> Categories -> X Category -> "Treat this category as a section".

This plugin allows you to organize the categories on your homepage into individual sections.

Tip: To make it look like this screenshot,

1. Go to the category ACP and set # of recent replies to 0.
2. Under Installed Plugins -> Lavender Theme, disable Masonry (or use the Vanilla theme)
3. Go to Appearance -> Custom CSS panel and add the following code:

.category-item .category-box .category-info {
    min-height: 85px;
}

Or just theme it however you want :)
