What's the maximum file size that can be uploaded?

...and is there a way to increase it?

Are the 5MB an issue for you?
We could change it in the source our you can simply adapt the changes in your local source files of the shiny app.

Well, I was trying to load a ~300MB file, maybe that's not a good idea at all (changing maxRequestSize doesn't really help)?

Did you change this line: https://github.com/mlr-org/shinyMlr/blob/master/server.R#L31 and then run the app? But yes, you might not want to run the analysis inside of an App as some processes can take a while and you probably want to save at certain stages.
