You know when you have a crazy complex flow, and it's hard sometimes to even tell where things are going? Especially those failure conditions that are all going back to a central Funnel or Port? I thought it would be visually very helpful if you could add Color to your connections, using the existing UI components in place for doing that.
I have a working POC, https://issues.apache.org/jira/browse/NIFI-6504. Which includes a screenshot and link to the branch. There are a number of open questions: * Should the markers (arrows) be colored also? * Should there be an option to color other components such as funnel's or ports? * I've also considered adding some additional line formatting options such as thickness and dashes, like the dashed green lines you see when creating a new relationship, or the extra thick lines that represent multiple relationships use now. * Should there be an option to adjust connection z-index so that users can make sure a connection isn't overlapping things in a weird way. The goal of this ticket is fully on making it easier and faster for users to visually understand a flow. Any feedback is appreciated! Thanks, Peter
