I installed exploratory for the first time today. I liked it. But then suddenly the app crashed when i navigated to charts tab. When restart it said that Server is running and you must kill it before running the app again. I killed the Rserver and it crashed the app again. Then the app started working.
I think the restart should be graceful. Also if the chart doesn’t show up, there should be some generic error handling or loading sign which keeps the user busy.
