It would be very helpful (for very large workspaces), if you could set a lock to the connection lines. May be in the properties or in the context menue.
In my case, there are very large workspace with lots of transformers an connections. It unfortunately happens, that you accidentally remove or change the connections.
Here one worspace with only some overlapping connections. Yes, i know that you can zoom in and choose one connection very well, but i'd prefer a lock to disable unintentional changes on the connections.
