Wondering if it'd be possible to have some flags or some such that'd allow us to specify the number of characters in the filename that the group by function will use? Currently, it seems to be hardcoded to use 0-9, A-H, I-P, Q-Z.
For example, pass it a value of 1 & the function would test against only the first character in the filenames and then create individual groups for each unique value thusly discovered. I suppose I could try to whip up some custom scripts or something for this (my script-fu often leaves a lot to be desired... )
TIA!
