Yes, this, exactly. However, as I've just recently learned how to make a sheet compendium compatible, I'm really balking at the idea that this would be all that hard. It's a basic database system. You set up a series of named fields, which a sheet must be made to correspond to. Then you fill in the blanks for each one. It's not exactly rocket surgery. If I, halfwit coder that I am, can wrap my head around this, then I'm really lost as to what's so hard about building the other side of it. :/ JoshLikesBeer said: +1 Not all compendiums are complete (especially if you use 3rd party or homebrew), and not all games have compendiums. The main problem I want to solve is that when I set up custom equipment, abilities, etc., I only want to have to set them up once. If, after adding a customized equipment, ability, etc to one character, there was some way to copy it to another character, either by dragging it from one character sheet to another or by selecting some option to add it to a custom compendium, that would be all I need. A workflow of setting up compendium items by configuring them on a character sheet first and then exporting to the compendium seems like it ought to solve (at least partially) the issue of formatting the data specifically for the character sheet that's going to use it. I like an idea someone upthread had about being able to have multiple compatible compendiums in the same game. You could have the main compendium plus any number of addons compendiums that add new things and/or override existing things. That would allow third party publishers to sell compendiums through the marketplace. I'd love to be able to import, e.g., Spheres of Power and Spheres of Might compendiums into a Pathfinder game. What I don't want is to have to keep setting up the same sphere talents over and over for each character and NPC. Just to be clear, this isn't meant at all in a rude way. I'm just honestly wishing I could understand the difficulty!
