Why doesn't the flow tab have an error badge? Like the changed badge, this could improve the visibility of nodes with errors.
We could even extend the badges into the Explorer sidebar for projects with many tabs.
It was partly because the flow is SVG and the tab/explorer elements are html (so no immediate reuse) & partly time/iteration 
Nice. I might be tempted to use the explorer panel a bit more with that.
Can you show the "Has documentation" badge (flow, group and node levels) too?
(passing by)
I have a whole other layer of stuff for catching / handling errors in/on my flows.
Every tab has a name. Every machine has a name.
On every tab is a block of code that detects errors and sends a report back to a central machine to indicate the error.
I then have a GUI to see who/where the error is and I go the respective editor.
It too has the error/s caught and listed.
It isn't a lot of extra stuff and - probably - isn't prefect.
But it does seem to work good enough for me to see the node's name (ID) and I copy it from the text shown and search for it on the respective machine.
I can post the code if you want.
Thanks, is it related to the validation of a node's configuration?
No, sorry.
It is for catching errors in the flow when running.
(I can't read.)
