New Mosaic release!
Big addition is back-annotation, where you can tell the simulator interface to save for example an operating point to the database, and then add this data to a label in the schematic, which will then update in real-time. You can even save and annotate custom data from a notebook. Read more about it on the wiki https://github.com/NyanCAD/Mosaic/wiki/Annotations
A smaller change is that the default configuration does not sync to the cloud. This means no random "test foo" schematics show up when you first open the app, and you have to deliberately connect to a remote database to collaborate/share your design.
