One Day!
for now some notes...
Clicking on a "cell" cycles through the various states. On a "Signal" holding shift gives access to the non-binary states.
Double clicking on a "Bus" alows setting of the bus value. This is free text.
Clicking on a state and then dragging (either left or right) will copy that state along a waveform. The drag action is not shown as yet.
Double clicking the name of a signal allows you to rename it
The row and coloumn cursor is set by clicking in the axis areas
Inserting a new waveform happens above the cursor (or at the bottom if no cursor is set)
The button bar provides some useful shortcuts. Tips in the status bar (and popups) indicate what they do! They generally require a highlighted waveform.
Moving waveforms currently has to be done manualy by copying and the deleteing the original.
