I assume you mean loading a diagram using the menu button. I left it
this way on purpose . It is supposed to be a feature. If you wanted to
combine two circuit portions to one diagram. The new circuit should be
selected so it can be dragged to a new position. It should really be
called "import" not "open". Right now there is no button to clear the
screen .You should refresh the page or select all elements and delete
them manually. However refreshing the screen will not work if the svg
is loaded from url. Do you like the feature or dislike it ? What would
you suggest I should do to fix it? Maybe a button to create a new
document?
Thanks for your comment,
