A couple questions on the data flow user interface: 1. Should I be able to select multiple components? (processors) I would like to have the ability to start, stop, delete, align or move them to a process group together rather than one at a time. I've attempted various key combinations to drag the mouse over several and to click select multiple without success. Click and drag on the canvas only moves the canvas around, while clicking components either changes the highlighted processor or brings up the context menu.
2. Is there a UI that clears the entire canvas? I read through the User Guide, so apologies in advance if I missed the answers. I am working in Chrome 46 on OSX 10.10 and Nifi 3.1 with NIFI-1077 applied, but experienced the same behavior with the Nifi 3.0 binary.
