SuzyQ: If I understand you correctly, one of the three top-level icons on the home screen leads to a set of screens that's essentially useless except for occasional housekeeping tasks. I can copy files from the "Apps" screen to the home screen, and I can organize the copies, but I can't organize the originals in any way. I'm a new user of Android and I'm trying not to judge things that may simply be different from what I'm used to, but that sounds bizarre.

Anonymuss: I tried what you suggested. I'm not sure what it's doing, but it's not doing what I want. It seems to do about the same thing that my original experiment did, except that the copied icon appears in different places on the home screen, and sometimes doesn't appear there at all.
