Disclaimer
This software is (very much) in alpha version-state. It works for simple use cases, but don't try to do complicated things. I.e. there is a bug where copying from an edited file, pasting in another, then writing the edited (1st) file to disk, could potentially change the other file-view. So keep all your write-back-to disk edits to 1 file for now :)
