Idea: Stacks: find personal productivity tech stack

I have been working on building the most complete directory of all of the tools in the productivity space (join the community at: https://www.reddit.com/r/braintools/). A big undertaking I know. One of the things that keeps popping up is integrations. I asked yesterday and it seems like a lot of people are using multiple apps. Which makes sense, but is new to me. This got me thinking of a directory for just that, finding your productivity “stack”. A place to go find the group of apps that are validated to integrate together and work for your use case. Each stack would have a guide, courses, templates, and maybe even discount for using the stack. Thoughts? Should I start building it this weekend?
