There are a couple of things that I think would be useful. I frequently connect to only a handful of hosts to watch log files scroll by or make changes.
1. Tile down option, instead of tiling right then down and leaving a bunch of room at the bottom of the screen, tile down first
2. Tile to full (or almost full) screen, if there are 4 windows and I have AxB real estate, make each window 1/4 A x 1/4 B
