    first of all thank you for this great tool! It helps me a lot while developing and debugging distributed applications.
    During my daily work I’ve found some issues I’ve mostly already reported on your issue tracker.
    Is there a way to contribute to MQTTfx? Although I’m not mainly a Java developer, this way I would be able to fix some minor issues myself and send you a pull request, this way you don’t have to do all the work alone 😉

    Best regards,

    I just installed under SUSE Linux and I get a startup error. The top few lines of the error log are:

    I’m not a Java person so have no idea what is wrong but it looks vry basic like a path issue.

    I installed MQTT.fx using the install script and am running it as root.

    Looks like a great package. Unfortunately it does not run on my armhf processor (Orange Pi PC with Armbian)

    I checked the repository and there are only Windows 32/64 and MAC binaries there. Any idea when some Linux versions will be available?
