Drybreeze, thanks for the images, pictures are worth a thousand words, and I enjoy seeing the way different people use the software. It often sparks new ideas that I can incorporate into my Brain.
It looks like a well thought out and useful database. I think you will get more value out of using tags for generic types, especially from a reporting/grouping standpoint, but ultimately it's whatever makes the most sense for your workflow and requirements. Like you, I use Thought icons a lot in my database. It makes a big difference for me to be able to have a visible indicator of what the thought represents and brings the database to life. It works so well for stamps, as you can enjoy the collection even as you maintain and update it. I agree, there are quite a few circumstances where compiling values would be useful. I hope this is implemented at some point in the future. Enkidu, I really like your use of materials as child thoughts. When I first saw them I thought "wait, those are groupings, why aren't they parents thoughts?" But then I followed the logic through and realized that they are what the art is created from, and it makes sense both a logical standpoint and makes a nice alternate perspective for creating visual groups. Thanks to both of you for sharing.
