WSM feature request: drop-down lists

The use of drop-down lists instead of pop-up menu's would allow users to type in the file, layout, and script names rather than waiting for a list to populate before being able to select it.

This would be very handy for filenames because to refresh the list of files I have to go into the admin console, disable to option that requires authentication before displaying hosted files, go back to WSM, refresh the file list, then back to admin console to enable that option again. If I could just type the filename, it would be exponentially quicker/less frustrating for me.

Layout and script names aren't quite as annoying, but I still have to wait for the list to refresh before I can select a new script I just added. Again, it would be much less frustrating to just be able to type the layout/script name.
