Re: Inkscape not saving Layer rename’s…
Don’t know if you’re using a Mac (OSX), I am and had the same trouble.
The Mac version of Inkscape has not been updated in long time (though, I haven’t checked in months). They posted an FYI about that. But, I can’t say that’s part of the problem.
However, I figured out the trick: The bad news is I can’t find my full notes on it. The good news is that I somewhat remember enough to maybe help…
It has to do with accessing the layer panel.
If using the panel tabs, the layer tab at bottom left or, in any other way, it won’t work.
However, if you access the Layers from the Main MenuBar, then it worked!
Also, sometimes saving as Plan SVG will enable Ink to properly load the layers into the layers panel (but, don’t count on it).
FYI - Gravit. Like most all software org’s, they mess with it and break things. I stopped updating. For Parts, just delete the “Vector-sizing…” from the xml file.
