-vpype commands could be performed differently: 
- - 1. Work with current selection (line-wise): we could get the selected nodes/groups and check if those nodes are paths. If yes we could convert them to polylines and put it into vpype using doc.add(LineCollection, Layer)
- - 2. We could execute vpype on the complete document only (svg file handling, possible as one layer or multiple layers)
-      working line of code (example:) doc = vpype.read_multilayer_svg(self.options.input_file, quantization=0.1, crop=False, simplify=False, parallel=False)
-
 Todo's
 - allow to change pen width / opacity in vpype viewer: https://github.com/abey79/vpype/issues/243
 - command chain is really slow on Windows (takes ~5 times longer than Linux)
- add some debugging options to remove deprecation warnings of vpype/vpype_viewer
 - allow to select other units than mm for tolerance, trimming, ... At the moment vpype uses millimeters regardless of the document units/display units in namedview
+- handle styles of layers
+- allow to select single layers instead of whole canvas (4th mode)

This command may be used together with linemerge for cases such as densely-connected meshes where the latter cannot optimize well enough by itself. This command will filter out segments with identical end-points. Note that since some paths (especially curved ones) can be made of a large number of segments, this command may significantly increase the processing time of the pipeline.</label>
