I thought 1 and 2 were already there.

3 would rock. I know this works to some extent but then dies. I'd much rather have the option of using a "get the file" (which would only appear in the right-click-menu on selected files in the downloads window) command on selected files and know that I can walk away and LimeWire will search and DL the file until complete (24x7). I find it very frustrating to have to manually perform searches at random times throughout a day to complete a DL.
