Filling path to data manually in CrystFEL GUI

[XrayViz]

It would be great if one can fill the path to data by copy-paste instead of navigating through folders.

I'm improving the data import right now, but there is actually already a way to do what you want - it's just not very discoverable:
Open the data import file chooser as usual, then simply type "/". The navigation buttons at the top of the chooser window should be replaced by an entry widget. You can even paste directly with Ctrl+V (or applicable paste shortcut), without typing "/".
Hope that helps!
