Feature Request: Storing data from file input

[wincowgerDEV]

I love this package it's extremely easy to use and has so much functionality. One thing I have trouble with currently is that people want to analyze large datasets on my shiny app in their web browser. It would be amazing if this tool could also store their data from file inputs so that I don't need to store them in the app for them.

When trying out the tool here: https://r2apps.shinyapps.io/shinystoreplus/

I was not able to get a stored file to stick around after a refresh. Perhaps I am missing something though?

Where I am trying to get the file to store and persist:

Example File: testdata (18).csv
