I think the 'first','previous','next' and 'last' buttons should not only be in BLOB-viewer itself but also in DATA and RESULT-panes. Also Alt+arrow_down for last and Alt+arrow_up for first would be nice (or Ctrl instead of Alt – what is most standard?).
If there is one ore more BLOB-viewer instances open they should load with appropriate data when focus moves to another row using arrow keys or buttons.
It is no problem I think, because Ritesh told me yesterday that GUI-work is not difficult at all 😛 😀
