Has a few quirks, but overall works well. Its best suited when you want to integrate with other tools. Most other wx code generators try to be a full IDE which works badly when working with multiple toolkits, libraries or buildsystems. Its a lightweight tool that does the job of generating code from a drag and drop UI, once you work your way past the initial rough edges. Haven't bothered with custom widgets, and the program would be much better with an "undo" feature. All in all, several orders of magnitude easier than trying to write layout code.
Hated it. Boa constructor is way better.
