The problem:
If you have complex flow with a lot of IF nodes, all IF nodes will get title as “IF”.
Its complicated to read and understand flow without opening each IF node and checking the condition or\and Note.
Solution:
Add field description to the IF parameters block and display it as a subtitle on the flow screen.
Would the description have to be so long that simply renaming the node accordingly would not be a good option?
Anyway displaying the “node note” underneath it, if specifically selected (could be a setting underneath it, to use as subtitle) could be helpful in many cases. But would also only work for very very short notes.
