We fixed a few things we overlooked in the last version:
* Lights on the ECUs will now flash when a row is blocked.
* If a row does not have a magnetic ball it will be drawn in a dark color.
* When you shut down your pump(s) to deal with a blockage, the app will remember which rows, if any, were blocked and will keep flashing those lights on the ECUs and on screen.
We also updated the user's manual in the app.
