Hello Alex.
During use NEXTGEN Gallery I faced with need to add following features:
1. NGG already use import folder with images and upload zip-file. Merge please this two functions for import (from server) zip or tar.gz file. Gallery name can to create from archive name or folder name in archive.
2. Allow display all images on one page of gallery (to remove the limit of 50 images per page).
3. Add function about new(update) post generation (as draft) by preliminary template from manage gallery menu.
Thank in advance!
