I'm trying out the filer and love it, except for one annoyance:
When the mini-buffer is active on a multi-item List View, then the
mini-buffer covers the last item in the list. Naturally, this doesn't
happen in the case of a single item in a List View, as the window must
enlarge to make room for the mini-buffer. I've found that this isn't a
problem in the Icon View, because it appears that an extra blank line is
reserved at the bottom of the viewing window, and the mini-buffer uses
that space when it is active.
This is all under the condition of always auto-resizing on a filer
window that hasn't reached its maximum window size.
