Having just done the initial update of the REGS guide, I have some questions about Mod Picker.; some of these might be about features that wouldn't be implemented or considered for a long time. They might have been answered previously; I did read all the posts but I could have missed something.
1. Different packs may need different installed versions of a mod. Since all of the mods are in MO I usually add a pack name at the end of the mod name (e.g., " - STEP") to indicate which version it is. Does Mod Picker support this or some other (and perhaps better) way to have different versions of a mod or is it at least indifferent to it?
2. I saw comments about creating Fomods. I was wondering how these would be created? Will there be a tool with UI input that allows creating or editing of Fomods; as one example supporting an "install for the xxx pack" option?
3. When installing mods that include portions that will be merged (usually patch plugins but sometimes also resources) the installation might need to be different than the standard install if the patch plugins need to be put into a separate mod. Merge Plugins supports copying resources, but it doesn't seem to support making this selective by plugin. Often a patch plugin that will be merged is part of an overall mod that includes multiple plugins and resources, but typically only the patch plugins are merged. The merge in the REGS guide for "Interesting NPCs" is an example of this. It includes some patch plugins and a mod with both plugins and resources. The patch plugins were in most cases initially located along with the rest of a mod.
4. Dreadfloop gave an example of edits to "Relighting Skyrim" for using xEdit to edit a source plugin vs. creating a patch that included only vanilla records to override onea in RS. With location mods it isn't an either/or situation. There are several examples in the REGS guide of using xEdit to remove sets of records associated with a particular location. I am not aware of any other relatively straightforward way to do this.
