I wrote my own terminal emulator stack. I was annoyed that the colors were often unreadable on others and that shift+page up wouldn't work to scroll from inside gnu screen that I used to use. So I rewrote the whole thing from scratch, my own terminal emulator and my own replacement for gnu screen. The terminal has both a custom palette and refuses to display certain combinations (if you ask it to do white on white, for example, it will do grey on white instead) and forwards various things like the shift+page up keys all the way down (and on the other side, commands like clipboard paste request all the way too), so when I ssh to the desktop and attach the session, all my habits still work. I know it sounds like overkill but it just really bugged me to strain my eyes and have to hit different weird keys depending on where I was.
