I believe WordPress could take advantage of the "favorite" feature to add a similar functionality in the core. At the moment you can already favorite plugins at the wordpress.org repository and view them via your site's admin (which is a handy feature that I use all the time).

The only problem with that is that you need to install all the desired plugins one by one, while it would be much better to simply add a checkbox next to each plugin and a button "bulk install selected".
