Stack Light Frame Rejection

Guys,  as an example, if we had 100 light frames to stack and we select to want 75 of the 100 for stacking, how do we view a list of the frames accepted and rejected?  It would seem like your software would deselect the light frames before stacking but it doesnt, so I have no idea what is being stacked out of the 100 frames.  I want to make sure bad frames are not being allowed and good frames kicked out.   


Also, when can you implement a blink function to the software to help speed up the good/bad file rejection?

The frames selected for integration show in a column - I believe its the quality score column. You can also choose what the criteria is for selection, like quality or star shape - in the "weights" setting, and you can sort the file list based on quality, star shape, etc. - right-click on the list for context commands like sorting.
