- Shows a tree-like view of elements in a script file - top-level entities, members within objects etc.
- Relatively low memory footprint
- Loads and responds reasonably fast even on somewhat old computers
- Syntax highlighting
- Actively maintained
- Runs on modern Linux distributions
- Can fuzzily lookup definitions of functions in other files, even if their relations is not formally or properly defined (otherwise I'd need it to be a full-fledged IDE with a bunch of complex logic).
- Supports light and dark color schemes
- Can also edit CSS and XML/XHTML/XUL files (with syntax highlighting and fuzzily finding definitions in other files)
- Runs on Windows
- Ongoing development
- Uses native GUI toolkits and doesn't "invent the wheel" UI-wise
