Maybe I'm missing something, but any changes you made to the application would not be saved, correct?

For example in Chrome assuming you downloaded something, you would have to specify the target location as your native filesystem, not the overlay filesystem in the docker container. Is it possible to do that?

You can bind mount folders between the host and container. (--volume option with docker for example) So that when you write in container's Download folder it would also actually be in your host's filesystem.
