Views duplicates

Ever had more than one view on a page and wanted to get rid of duplicates?

While I couldn't find answer for that question I just wrote this module to help me out. And it does job pretty well.

I have a news site that has different blocks of views showing the same content type, some of them show promoted articles, while others show some other different variations. But sometimes it happens that few views show the same node in them as it matches those criteria. So to get rid of that problem I wrote this simple module.

It gets node ids from the first view displayed on particular page, and alters query of the next view to remove those nodes from displaying.
