from the terminal easier. It has:

first-class mouse support (even over an SSH connection)
a Sublime-like file sidebar
double-click to select word, highlight other occurrences
configurable Sublime-like keybindings * (Ctrl+S save, Ctrl+Z undo, etc.)
copying/pasting with OS clipboard support
infinite undo/redo
syntax highlighting for 100+ languages
bracket matching
autoindentation
heavily customizeable via plugins
... many other features that will make you leave nano, vim, and emacs behind

if an existing file isn't found.

Plugins

Slap is fully customizeable and supports plugins written in JS. You can place
single JS files, or NodeJS packages, into ~/.slap/plugins/.

To write your own plugin, a good starting point is
slap-clipboard-plugin.
Please note that plugin packages must have "keywords": ["slap-plugin"] in
package.json.
