What’s next?

The Variable section requires immediate attention. Many of you requested the ability to delete and edit variable parameters. Also, the display of the variable table needs some modifications to improve usability.

Meanwhile, my colleague is working on undo-redo functionality and PWA (Progressive Web Apps) to give an experience similar to native mobile apps.

You can view current road map of the project here.
