Definitely so Rod; Mattia even compiled the 64-bit version of it (just noticed it). Can't get the external launcher to work, but, to be honest, I am happy to just export the SVG and be done with it that way anyway. Thanks a heap Mattia.

You need to set the full path of the executable to launch external programs in Plugins > External > Setup External Programs. (you need to enter it manually, that plugin is still a bit rough).

Tried doing so with quotation marks "C:\Program Files\GIMP 2.8\bin\gimp-2.8.exe", but the program takes out the slash "\" and I can't figure out why.

try with forward shlashes /
although this may be a bug will take a look

[edit]
Yeah, it was a bug, not of the blugin but of the way Knotter handles plugin config.

Haven't tried your reverse slash idea yet, but again, I rather just save the SVG and port it in the GIMP. Very grateful for your continued improvments to Knotter and glad you figured the 64-bit compile issue Mattia.
