Any chance you can add an extra decoded.txt file (different name like all_decoded.txt) that is a running list of all decodes? This file could then be uploaded at regular intervals with a simple batch file to a page similar to

This might be easier than G0LUJ's presentation of the decoder GUIs ... and it would give the ability to scroll back in time. Suppose it could be taken a step further by separating out the decodes to different .txt files based on the different modes.
I know your busy working on more important issues with the program ... just something to think about for the future.
