Version 0.14 of the uGFX-Studio has just been released. It addresses issues regarding the building of the preview application both for Windows and Linux users. The preview now works with Ubuntu 14.04 LTS too.
Another great feature the new release brings is the ability to specify custom user scripts that will be executed after the code has been generated. Possible use-cases are to execute a script that will copy all generated files to the project directory of the IDE that compiles the code for the actual target hardware. That way the user doesn't have to manually copy files around anymore.
