1: GPRename remembers the last directory, but on my system, one has to scroll the side-pane quite a ways to to point where the highlighed directory is visible.
==> position the contents of the sidepane so that the highlighted directory is centered (or at a minimum, visible in the side-pane).
2: For Numerical renames, allow the user to set the number of digits within which the number is zero-filled.
For my photos, I like to have a prefix (indicating the camera), and then a 4-digit number, zero-filled.
ex: for a new camera, I would not have taken 1000 or more pictures yet, but if I use GPRename to rename 75 pictures, I only get 2 digits of numbers, with zero-fill if number is < 10. For 175 pictures, I would get only 3 digits, with two zero-filled digits if number is <10, and 1 zero-filled digit if number is <100.
Whereas, I would LIKE to have 0001-0075 for the first case, and 0001-0175 for the second.
Thank you for reading my suggestions.
