There are 2 issues that need fixing on the stock in Screen.  

1. The initial search box should have a search button next to it. It should not have a button that opens up a new manual search bar.  This should be a secondary feature separate in appearance from the initial search box.
2. Once the manual search box is open, it utilizes only a small percentage of a screen and is not expandable.  When you attempt to book in a product, you have to shuffle all the columns around to see what you were doing.  I had raised this with Linnworks support approximately 6 months ago and it's supposedly on their list of things to do. I thought I would put it up here to see if we could get some votes to prioritise this.
