I have two use cases here:
1) A single tool that I want to connect to several tools (e.g. an input connecting to a number of selects)
2) Several tools that I want to connect to a single tool (e.g. several inputs connecting to a single union tool)
The current interface requires that I establish these connections by connecting the tools individually. It would be great to have the ability to have a right-click option. Simplistically, it might work something like this...
1) Select the tools that you want connected to a single tool (e.g. all the selects); Right-click; Get connection from Tool...{drop down list}
2) Select the tools that you want to get their connection from a single tool (e.g. all the inputs); Right-click; Connect to Tool...{drop down list}
