A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
I have a set of nodes with different colors/styles. I want to select one set of nodes with specific styles.
for example: in attached screenshot below, I want a keypress / find option to select all ellipses or select all green color nodes only.
the selection is easy with 5-10 nodes. but when the diagram gets bigger its difficult and style based search/selection might be helpful.
