Presets.
Presets contain all your settings for any certain tasks, including date, time, attributes settings, all variables and the renaming template. You don't have to save presets for a one-time renaming process but if you want to quickly restore all settings at any time, you should save the preset. You can do it in the main window, preset section. Use [save], [load] and [delete] buttons. The preset's name shouldn't contain any unallowed by the OS symbols because a file will be created with this name.
