gifs from pngs.. a few questions, starting with:

[mr_ron]

how do i reverse frame animation order where i have maybe hundreds of frames?   seems odd that the default should choose to do everything backwards.

also is there a way to have the default frame time anything except for 100ms?
if so or even if not is there a way to change frames times over several frames at the same time rather than changing them individually by editing their layer name?
