With new UI in Spotfire 10, it is harder to navigate to files that are multiple folders deep in the library or in very long lists.
In the "Library Administration" menu item, the library is presented similar to a Windows File Explorer window where you can click inside the window and type a letter (or a few letters) and you will jump to the first file starting with what you typed. This is very handy in long lists to avoid scrolling.
However, in the new "Files and Data" menu, this behavior does not work.
Please note, this is different than the search option because it behaved instantly whereas search by name requires processing and is very slow in large libraries.
