I can't believe how easy this is - great video!
Just tick the box and paste some code and you get full self-updating app :).
I guess it could work for any Go GUI app if you don't need the Fyne UI elements too?
For those that might be interested, we have integrated our previous open source work on self updating Fyne application with our build and delivery service. Have a read and let us know if you are interested or have any questions!
