New to Smartftp and I've got 4 questions

Hi, I'm all new to smartftp, just switched from flashfxp which I've been using for ages

But I've got 3 simple questions that I haven't been able to find out on my own.

1. What is hot items? Some items on the ftp site I'm browsing got the foldername in blue and I checked options and it says that that is a hot item, but what is that?

2. In flashfxp you got a total time left time for all time left for your queue. How do I show that in smartftp or isn't that possible? Global queue show me total size, for the folder, and it show me speed but no total time left for the folder

3. Is it possible to prioritize directories too? I saw that you can do it with files and tried to add a dir name but it didn't dl that one first, maby something that should be possible in upcoming versions?

4. Is it possible to exand all dirs in the global queue? Let smartftp list all dirs before it starts downloading anything so that I know exakt how big my queue is and not only list the current dir I am downloading.

I kow bumbping isn't good but I really would know the answers to my questions.
