"SDLTM Import Plus" is really a great App if you want to see the file name where a certain segment has been translated. The fact that a field is automatically added if not present, is really useful.

A similarly useful information in the SDLTM would be to see DSI info stored with a segment or with a group of segments in an SDLXLIFF file.

I admit that the approach would be slightly different, since for DSI, the App would need to loop up DSI fields in each SDLXLIFF file (each might have different DSI infos inside), since they may differ from file to file, whereas a file will always have a filename. But nevertheless this would be a fairly useful information for reference purposes and maybe even for filtering for certain DSI infos coming from old translations.
