Elder Scrolls Forum: (WIP) TES Plugin Tool - cleaning plugins, merging leveled lists

Right now this utility performs two functions - cleaning ESP/ESM files and merging leveled lists for ESP/ESM files. I may include some other features in the future (I am thinking about dialog merger and some helper function for the The Lighting Mod (to generate ambient light settings for all cells in all plugins) next). But for now it is just cleaning and leveled list merging. Before I go on describing them - THIS IS STILL BETA. I tested it but I am not sure that all bugs are taken care of. So treat with caution.

CLEANING ESP/ESM FILES

This function will do several things:

Remove any default GMST records (all 72 of them);
Remove any records that are identical to the records found in the morrowind.esm, tribunal.esm or bloodmoon.esm. This includes objects, dialogs, scripts, NPCs, lists - everything (with some exceptions noted below). This should take care of many situations when plugin does not modify some object, but it is marked as modified in TESCS and therefore saved within plugin.
Remove any object references inside CELL records that are identical to the references in the morrowind.esm, tribunal.esm or bloodmoon.esm.
Remove AMBI(ambient light) and WGHT(water level) fields from the CELL records identical to the morrowind.esm, tribunal.esm or bloodmoon.esm.

There are couple, of course, some exceptions:

Land texture (LTEX) records are never removed - for some reasons removing them sometimes causes errors and I was not able to find a cause. So they are not touched for now.
Cell (CELL) records are just cleaned inside - records themselves are not removed either.

Comparison is done against morrowind.esm, tribunal.esm and bloodmoon.esm. However, out of those 3, I use only those that are currently enabled in the morrowind.ini file. So if you have both expansions, but want to clean only against morrowind.esm (e.g., because you are creating a mod for Morrowind only), just uncheck tribunal.esm and bloodmoon.esm and cleaning process will use only morrowind.esm.

MERGING LEVELED LISTS

This function is very similar to the well known Horatio's utility "Leveled List Merger", however it is not based on the Horatio's code/algorithm and may (and probably does) perform merging somewhat differently.

Leveled lists will be merged only for the ENABLED ESP/ESM plugins - any non-active plugin in the "Data Files" folder will be ignored. Both leveled creature and leveled item lists are supported - and both are merged according to the same set of rules, described below. Resulting lists are saved in the file "Merged_Leveled_Lists.esp" in the "Data Files" folder. As usual, make sure that this file loaded AFTER all other plugins.

Now, rules of merging:

If any of original leveled lists had "PC Level" toggle enabled, final list also will have it enabled.
If any of original lists had "Each item" toggle enabled, final list also will have it enabled.
"None chance" value will be set to the MINIMUM non-zero value out of all original lists. Of course, if ALL original lists had it at 0, final value also will be 0.
When merging list items, only NEW items will be added.

Last point requires an example. Suppose current list has two "3, skeleton" items (both level and name identify unique item - "2, skeleton" is considered to be different from "3, skeleton"). If another plugin contains same list and it has only one or two "3, skeleton" entries - they will be ignored and not merged. If it has three "3, skeleton" entries, resulting list also will have three "3, skeleton" entries, since that third entry was not present in the first list. Of course, if second list contains "25, lich" entry that was absent in the first list, it will also be added. So, basically, only NEW entries will be added during merging.

Other stuff
Link to the current version (0.9 BETA) of TES Plugin Tool can be found at the end of this post. Detail instructions on how to use utility can be found in the text file included into the archive (READ IT!). Any bug reports are welcome - PM me or post here.

Of course, I welcome any feedback and ideas in regard to cleaning functions and merging of leveled lists - please post it in this thread or PM me.
