Few questions about edges...

1. Is it possible to selectively highlight/select an edge element and remove/hide it so when you show 'edges'
in the types list it does not show up (for example vertical line on the internal radius - hide)?
>>Noticed i can select the vertical part but there is no 'transparent colour' in styles.
Potential solution: Put these objects on "HIDE" Layer(Style) or script ??

2. Is it possible to change the colour of the edges to be a bit more subtle on some objects?
>> Likely I would use a custom STYLE for this.

3. Is it possible to make one object have no edges displayed so even if the type has EDGES "ON"
a few objects ignor the global setting?
>> As per #1?
