very happy that I could help, and thank you in advance for any feedback you may have. you are the first of whom I am aware using it on Ubuntu 19.04. There are not supposed to be differences among operating system versions because of Qt, but in software that is never a safe assumption
If you find bugs to report or enhancements to discuss, please post that on this forum. Please start a new topic when you do.
I have not used instagram, but I will keep an eye out on @codeture.
@slspencer - you may find this interesting as well.
I know that there are others in Germany and specifically some activity in Berlin with a lady presenting some workshops. please see these topics for more information
