save as a copy of a data source
Once you have found the "Save as a copy" feature in the Klip "Save and Exit" button you are glad that you do not have to rebuild every Klip right from the start; however if you want to reuse a data source that has some more complicated settings, you have to rememebr very well how you managed to do that the first time; so bebing able to save a copy of a data source would be a great feature too
