it would be nice to be able to export your tweaked sample

- export as .WAV : an option to export the tweaked sample as wav would be nice. that way you can reuse it in another project (even outside of hydrogen)
- export current settings : would create some sort of file that contains all settings you have configured in the sample editor. this way you can import and reuse those settings in another project. this could be a separate (XML ?) file, or a copy of the original WAV file that contains extra meta data that describes the editor settings.

this is all about re-using of the work you did in the sample editor on one project in another project (since the sample editor settings for a sample are stored in the project)
