I want to create a new frame that contains nothing but the mode-line. Especially not a file buffer.
Why do I need this? I use org-mode's clocking to time my work. Org-mode displays the timer for the current task I'm working on in the mode-line, and updates the timer in real-time. I use apps other than Emacs, so when I switch to them (e.g.. when using the browser or terminal) I still want to be able to look at the running timer. I thought I could create a new frame, but when I now click on the timer in the mode-line the .org file is getting opened in the new frame (which is already resized to show only mode-line) instead of jumping back to it in the first frame.
Here's how my mode-line looks (the blue bar) -- that is all I want on the new frame:
(Eventually I will have to figure out how to make the new frame appear always-on-top, but that is outside the scope of this question)
I use OS X if that is relevant.
