While testing #83, I found that running the app has the wrong info in the tooltip for updating to the latest appimage.
The tooltip says that the button is disabled (not true) because the program wasn't installed using an appimage (hasn't happened yet).
We need to figure out how to differentiate between an install that has run and one that hasn't so that the tooltip can then read this properly. Perhaps some null value in the config?
Perhaps #85 will resolve this?
