It works seamlessly and it very easy to understand.
No issues in setting up a project and start coding, good for getting job done.
Truly cloud based IDE with simple interface
Available as app on ChromeOS (another use of chromebook)
Good language support
Stable and does not crash or data loss.
Has GitHub support which is a major plus point,
Template projects available are for good for learning
Not many GUI customization options, default black-grey theme and language code color is default and cannot be changed.
FTP/SFTP is always required to update the files directly, however local storage option would be welcome. Sometimes it takes long to download projects while setting up.
Many many pros than cons.
Must try cloud based IDE for coder on the move. Good for getting the job done easily.
