1) having a GUI top-bar of the commands. This was like P-Code and UCSD Pascal, it was the permanent hint feature, that followed your context. It was a big HCI design issue, and I think helped inform how people expect menus and bars to work
2) reveal markup. Huge. Being able to "see" the embedded control char elements of the textual display. Something I think other tools should have picked up on more. There's a mode in VIM which does something similar.
3) it was fast enough. for a small memory model. We're talking pre MMU chips here. Dos.
