It might be nice to be able to abort a long-running PD stack run. In some cases you have to deal with very large amounts on data and you might only be interested in decoding up to a certain point / sample number. PV could e.g. provide an "Stop decoding" item when you right-click on the PD stack's "arrow" icon on the left (there's already a "Delete" there). This would stop further decoding, but leave the already decoded annotations etc. around for the user to browse. As an additional, optional, feature it might also be nice to then have a "Continue decoding", if (after annotation inspection) you find out that it would indeed be interesting to see some more decoded data.
Note: This is similar to #304 and has a certain overlap, but it's probably not quite the same. Might be neat to have both facilities.
