Ugh. This is exactly why closed source code bases suck. If you guys weren't into profits and competition and all that I could simply build on your code directly and improve "the product" for people who use the same tools I do. As it currently stands, features that won't greatly increase your marketshare never get on the "roadmap." Moral of this story: capitalism stifles good features and thereby degrades code quality. Meanwhile sharing is caring over at Github ;).
For researchers a command-line session often involves interactive plotting. Being able to display a quick pop-up graph through X11 would be extremely useful for users using R, Python's matplotlib, Gnuplot, etc. on a daily basis. I'm envisioning the graph being displayed over the keyboard, and then on first key press it would be dismissed, enabling the user to immediately see the prompt again and type in the next command!
iSSH apparently offered X11 forwarding, but maybe just on OS X?

Developers, from your experience, how tricky do you think this would be to implement?
Yes, wake-on-lan functionality is a must-have!
