Is there any way to make omni complete popup a list of suggestions but not immediately add one of them to the buffer? I find omni complete very useful but it's incredibly annoying that it auto-chooses one of the entries. I'dprefer it popup the list of suggestions but not modify the buffer.
If I understand your question correctly, I think what you need is: :set completeopt=menu,preview,longest:help completeopt for more details.
