aeva-slicer binar does not seem to have Data / Segment Editor / Meshing tabs as in demo video
Applies to "AevaSlicer-1.2.0-linux-amd64" on "Ubuntu 18.04.3 LTS"
aeva-slicer demo describes three tabs "Data", "Segment Editor", "Meshing" in the demo video. The version noted above has different tabs instead (see figure). Data, Segment Editor, Meshing are still accessible through the modules. Maybe the version in demo and the binary noted above do not match.
