### 5/5 — Amazing

*2022-01-07*

This is probably the best app out there, it so helpful when it comes to factorio. Thankyou for such a great app.

### 4/5 — Super Useful!

*2021-02-15*

Having this available as an app is amazing. Already using it instead or alt-tabbing back and forth. 

Suggestion/requests - the ability to save-state when closing the app. If I have it set up to show me all sciences at 1000/min I hate having to redo the selection if the app is closed. Also the ability to “turn off” pieces of the puzzle that have already been processed like you can on the web version.

**Developer response:** I plan to implement the feature to save the configuration in the next release (1.0.16)
