Place files on plate, but have a say on how they are arranged on plate, without doing it manually.
Why is this useful?
There can be many reasons that an automatic arrangement on buildplate is not ideal, that could include holde in buildplate surface, screws and simply a need to tidy things up, so it looks pretty while printing.
This will allow to quick and easy place things as you like, while keeping things tidy.
- Do other slicers do this?:
No they do not, at least to my knowledge, but other kinds of software does. See for example how it works in Inkscape.
