Tying up few loose ends in the UI.

The above screenshot is the first option for navigating between the errors in the log pane -- see two red arrows next to the "x" in the pane header. The second option is this -

This time the next/previous arrows are in the error entry itself.

I like the second option better, because it's contextual and I think it's more obvious. However, first option is superior in functionality because it allows jumping to next or previous error when there's currently no error visible in the pane.

Still deciding...
