If you like it, you should check out era X Windows managers with a multi button mouse. Same hierarchical start menu, but bring it up from any location on the desktop with right mouse click! Then most simple apps don't really need menu bars or windows controls, just maybe small resize handles at the corners, use right click to do the rest as well. Once you created a perfect arrangement for each virtual desktop, save it and have it perfectly recreated on startup. With not a pixel wasted and apps themselves not wasting much white space, it becomes possible to have all the tools you need for your workflow side by side rather than constantly hunting for the right overlapping window. Plus, workstations had keyboards with dedicated copy/cut/paste keys, rather than remembering to press Control-Shift-C in Terminal and Control-C elsewhere and half of the time killing your current command by mistake.
