Now that I think about it the widget might not be that difficult, it will just make a call to get the widget data and display it along with some code to let users vote and a link to the actual topic where the poll is located. So most of the code that is already in the plugin can be utilized for the widget. The widget would need a pollId setting in the ACP>widgets to let you display a poll.
We have many NodeBB plugins that are no longer maintained, but people still want to use them.
Can we fork them to NodeBB Community (or other) namespace on GitHub and publish under @nodebb-community (or other) namespace on npm?
To allow the installation of those plugins from ACP - we can increase the range of search to this namespace too.
