The twist here is added Category/Subcategory entries in the 'Custom' placeables list. Having seen 'Expanded Placeables' by Merle, I liked the idea but was dissappointed that he didn't provide expandable lists like 'Special' expands to become 'Custom 1-5'. I dug into the placeablepal.itp and created the needed structures. I have added 9 expandable categories containing a total of 63 subcategories. (see screen shot for example expansions). Having this nice structure I added a lot of placeables to it, currently it includes placeables from 61 placeable packages from the vault. Merle noted that this technique didn't work in the DMClient, which is true but it does make them sort better there due to naming convention. Please check the 'ReadMe' for details of how to install as the process is different for NwN or SoU.
This package will now work with either NwN 1.29 or SoU 1.30 and it does so with a single placeables hak and erf. It does have seperate master haks for NwN or SoU.
