No need for template.
There should be support with SpigotMC. You can search SpigotMC for plugins. If the plugin costs money, then you can't download it. When you try to select it, it opens another GUI like normal with a Redstone Block in the middle names "Unable to download." with a lore of "Click here to buy the script for $PRICE". When you click it, it's like clicking a link, it asks are you sure you want to open this link and it opens it in your default web-browser. I thought this would be good because my server runs spigot and I am running my computer on a separate laptop, I don't want to go to my laptop and find it on SpigotMC then download it, then reload the server (which takes like 20 on my server). Could this be added plz?

* I am running my SERVER on a seperate computer.*

Im going to look into urls first

Part 1 of 2 will be realeased in version 2.3.3:

This includes downloading plugins by pasting a download link in the /inst load [url] command

Part 2 would be adding support for the acctual search on the spigot page

You could use spiget.org, a wonderful implementation to spigots resource site.
