In many node editor, the connections between nodes are mostly curves rather than straight lines
Visually, this can achieve better results. Can you consider using Bezier curves, etc. instead of the current straight line connection?

There are some examples:

• [

For example, we want to remove /home/adavidoff/git/balls/ and the configuration contains --path="$config/../balls/".

The fix needs to not just perform path substitution, but also convert to absolute paths so that the input can be successfully compared. See nimph/config.nim in the bizarrely-named removeSearchPath procedure.
