The main thing I want from a terminal text editor is to have the same keyboard short cuts as any other program I use, which is why I use micro. In the screenshot I see Ctrl+W to save as. Why not use Ctrl+Shift+S like any other program? Why not use Ctrl+W to close tabs, again, like any other program? I can already see myself closing tabs in other programs trying to save as, if I start using this.
There are limitations to which keyboard shortcuts are available to an application running in a terminal. And those limitations often vary per terminal.
