Multiple virtual desktops, my friend. If clients pop by and want to see how you are doing on their project then swap to the required desktop and every terminal window and every browser tab relates to their project and nothing else. You can also have a desktop with your own stuff on it, i.e. with all the distractions, and not have to fret about closing it all down. Pick up with your distractions where you left off. When you are done fixing whatever for project whatever you can simply close down the browser and terminal windows on that desktop, you don't have to sift through your tabs. If you do need to change focus from project A to project B then it is a simple switch, not a mess to wade through.
