The plugin manifest now supports new properties to better describe and present your plugins on Joplin Plugins website. Those are the icons, categories, screenshots and promo_tile properties.
Icon
This is the icon that will be used in various plugin pages, including in your main plugin page. It will be shown on the main result page too. If not provided, a default icon will be displayed instead.
Category
You can supply one or more category for your plugin - it will be used to filter the plugins on the website.
Screenshots
Again you can provide one or more screenshots to present your plugin on the website.

Promo tile
The promo tile is an optional image that is used to display your plugin on the main website page. If no promo tile is supplied, the icon will be used instead.
@laurent we really need a tab for new plugins, because we then know at least that they will work and it is always cool to find new plugins, and another tab would be also recently updated
While I was reading the documentation, I noticed that the id attribute in the manifest is actually not listed in the table, and I couldn't immediately see where the source for that documentation page is stored to submit a PR.
I did, however, add a small PR to add the promo_tile attribute to the Yeoman generated-plugin template.
