it seems that none of the “sort by” option do anything in the 1d view.
i assume features, means tie points?
neither name or index don’t seem to do anything either.
I only just noticed after all this time. that’s there is now i 2ds view.
that looks good. though i still would really like to know how many camera i have selected.
maybe a change log on future versions would be nice too 
what would you like to sort in the 1D window, or did you mean 1Ds?
yes, number of tie points, next to the images listed in the Camera poses tree of a component, is the number of features,
you can already see the number of selected cameras in the 1Ds,
