Paging for large productlists

When working with customers with a lot of products the listing takes quite a loot of time to load and filter.
Would be nice to instead have a pager functionality and an optional to select pagesize or all where default page size would be like 50-100 products.

Searching/filtering
After the initial search for products it would be nice to keep the initial filtering options (fields for Article number, Name, Description and dropdown for conditions) with the selected input. That makes it way more easy to work with the search if you need to update your search input.
Another good thing would be to enable editing for the selected conditions. As of now you have to remove your condition and add a new.
