Thanks a lot for this nice plugin :-) I have a delta printer and this feature was deseperatly missing in Cura !
I noticed a small bug : if there are some unicode symbols in some comments (° in my case), the plugin failed to save the file with the following error :
Unable to write to file pied piano: 'ascii' codec can't encode character '\xb0' in position 43211162: ordinal not in range(12
8)
Removing the caracter solved the issue, so nothing critical, but it'd been nice to allow unicode comments anyway
