Inu Games - Modular Snap System Runtime

First of all I want to thank you for this great plugin!

I have question about editing Snap Settings. I would like to use “Snap Open Only” and “Open Check Radius”.

In my case I have multiple + sockets close each other (5cm) and I want attach only items with **- socket **to those.
When I use Snap Open Only setting and set Open Check radius, plugin will also count **+ sockets **to this check so plugin thinks socket is already taken even if I don’t have any item attached with - socket.

So how can I edit “Open check” to count only opposite pole sockets?
Is it possible to change preview color (for example) from green to red when you are trying to attach item to closed socket?
