I have a question regarding Spaces, for anyone who has had the chance to use it or just for speculation: Can you designate a program to be on all of your Spaces? I find having multiple desktops very useful but I would like to be able to assign certain programs to be available on every desktop/space so I don't have to switch to that space to use it. For example, iChat or Adium. If I have a space where I'm surfing the internet and a space where I'm working in Photoshop while talking to a buddy at the same time, I'd like to have that window in both spaces, rather than having to switch from the Photoshop space to the Safari space (if that's where iChat was last) to answer the IMs and vice versa. In other words, I'd like to be able to have programs that one has to tend to often (like IM programs) to be on all (or at least more than one) of the spaces, so if you move to a different space you don't have to keep switching to the space it's on or drag it back and forth. I hope Apple either has or will put this feature in, as I think it would be quite useful! What does everyone think?
