Pro Build in terminal
Press F5 and code will run without the need to switch between windows.
Pro Actively developed Open Source
Which usually means it will remain free of charge.

Hence it is capable of showing the methods and inner classes of, e.g., a Java source file.

Spyder can plot graphs and provide the list of all variables.

Con Not very advanced
Similar to Notepad or Gedit.

Geany is not as popular as some other text editors with plugin support. As such it's understandable that it's missing lots of powerful plugins available in other editors.
Con Windows installer not digitally signed
Con The documentation is poor when it comes to debugging
Not a lot of information about debugging is available in the documentation.
Con Not beautiful
The default theme is not beautiful. And there are not many themes.
