a bug: the rectangle "drawn" with right mouse button doesn't stay in place. As soon as I click on something else (mostly the buttons-gadgets for thresholds), it returns to the previous position. (maybe this has to do something with the source, avisynth'd and cropped)
a feature request: Also, the rectangle cannot be drawn by dragging in bottom-right to top-left direction (message: range check error). This is sometimes needed when the bottom-right corner has better visual indication.
another feature request (low priority): inter-line height to be able to be bigger than 40.
a community "please": some good values for thresholds (or tutorial, as mentioned). No matter what I do, I end up with subrip recognizing only parts of letters (too thinned) or ugly big areas (the two fill options don't help). The source is very clean, BTW.
thankyous: to the authors of the program.
