Ui not accessible to screen reader users
The orca screen reader is unable to read the important parts of the UI. The only things it reads are the zoom in and out buttons, the text in the middle that dictates how much zoom should be applied, the toggle button that is the menu that brings up the about helvum option, and a scroll pane. This is extremely easy to reproduce, start Orca and open helvum and tab around the interface and the inputs and outputs are completely skipped over. There should also be a way to connect and disconnect outputs and inputs that does not require dragging, as this is not a feature implemented in Orca and probably will never be.
