You will need to install a user script manager extension to install this script.
In the original version of the Collection page there are at least two major flaws:
* it is not possible to search bundle by its name since it is not displayed anywhere on the page in the normal text form;
* both owned and not owned bundles are displayed in the same list and you have to look at each to figure out do you have it or not.
My script adds textual bundle names to the page which automatically enables all standard search features on the page and moves not owned bundles to the bottom of the page below the list of owned bundles.
