Middle Pane

[#1]

Please add the features for Middle Pane in the next release of ACT.  This is such a time saver.  If you are not familiar with it, do a search in the community board.  Apparently it is no longer compatible with ACT.

Don't forget to kudo this request.

Vertical panes would be great too.

Fixing the middle pane and adding a vertical pane. would be much used and much appreciated;
