Many times I want to reduce the total number of frames in a GIF. To do this now the only way I know of is to delete the frames one at a time, which is very time consuming. Could we have a "Delete Every Other Frame" or, "Delete multiple frames-select" option please?
If you're converting video to gif, it can be done in the corresponding dialog. Otherwise, you're right, select and delete one by one. I'll add your suggestion to the list.
