replacedelement.path = replacedelement.path.to_absolute().to_superpath().to_path()
|

- maybe option: break apart while keeping relative/absolute commands (more complex and not sure if we have a great advantage having this)
|
||||
- note: running this extension might leave some empty parent groups in some circumstances. run the clean groups extension separately to fix that
|
||||
- sort to groups by path type (open, closed, ...)
|
||||
|
||||
- important to notice
|
||||
- this algorithm might be really slow. Reduce flattening quality to speed up
