Unless I’m missing something, I don’t seem to be able to load my existing models back into the editor.
The load button doesn’t do anything. I don’t get any kind of file chooser and I have a filename in the filename field (the program seems to remember the last one you used).
With the system remembering the filename, but not retrieving the model. I’m worried an accidental press of ‘save’ will overwrite the existing model with a blank one, or whatever is in the editor. (I haven’t yet tried to see if you get an overwrite warning).
As an aside, I think it would be helpful if you had an option to move the model’s location within the grid. That way if you found you needed to resize the work area you could move the model to centre it and add bits accordingly.
