This is a MAX influenced idea but it will be extremely cool to have it. I'm talking about Buttons and Knobs right in the Edit Pane. It could be special modules for such task or even it could be the modification of the normal Panel knobs set to be invisible in the front Panel. So you can drag such Knob around the structure by its header and click/drug on the Knob to control the values. For Core also would be great to have this inside. Could be a very useful tool for debugging or as a temporary solution while building-testing. I use Constant modules very often to do things very fast by connecting them to other modules instead of making a Knob, setting the properties, etc. Cool that in R6 now we can type values right in the Constants. But Buttons (switches) and Edit Knobs will be even more useful. Just look at the recent Knob module, it have a Knob icon on it, imagine you could drag it up and down! Also some Numeric Readout could reflect the changes right on the module inside the Edit window.
