Next two features will be Progressive Web Apps (PWA) functionality and undo/redo. We should publish them in two weeks a month.
After that, I'll be working on math components, and my colleague is going to work on sharing diagrams through a link. The biggest challenge there is to figure out compatibility with newer versions of the PLC Simulator. Let's say that we changed the structure of the store where we are saving the diagram to implement new features. Now the old links refer to the old structure, so you won't be able to display them correctly. We want old links to be compatible with new versions, so once saved links are always valid.
