When running the table to geodatabase tool, allow the user to specify output feature class name like the vast majority of GP tools. Right now it just accepts the name of your Excel sheet (e.g. Sheet1_) with no opportunity to change. To do that, you have to pop over to your catalog and rename it after the fact - something I like to avoid, since this is not recorded in GP history. For that, I guess you could use the rename tool, but why the hassle...
