Allow to select folders for import
I'm a data science student and one of my use-cases is importing 100,000 small json files in nested folders. I copied them all over to one folder but selecting all of these files tends to lock up the GUI. It would be nice to be able to select a folder for imput.

Actually I just did a `find . -type f | wc -l` and found that I have 12,839,411 json files.
