My issue was/sometimes (like in the attached image), is that I might have nested for loop blocks withing blocks and utilize more than one output.
With the brown 'network' boxes as they are it can make the network look messy and hard to organize.
Sometimes it's not ideal to make use of object merge nodes and/or use scripting to reference for each outcomes and/or intermediary results.
I'm making this post with a title so that others in the future that need to know/make us of can do so with a forum search.
Here's the response I got from support:
...From our developers:
RMB on the Block End node. Flags:: Descriptive Text Flag
Turn that off and you also lose the convex hulls. This can thus be done per-node if you have terminus nodes that uglify your network. So you can keep those smaller boxes but lose the big ones....
One small note. On my system/Houdini version it's not 'Descriptive Text Flag' that is either ticked or not but rather 'Display Text Badges'.
