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.
Can use a lot of memory (several GBs).
Con Can sometimes become very slow, freeze, and become unresponsive
It becomes extremely frustrating when you have to wait for the text you've typed to appear in your editor. Furthermore, during these freezes the editor does not always queue what your're typing, so you might have to wait > 15 seconds before you can continue your editing. This quickly affects the concentration of a developer, causing flow interruption and general performance degradation.
