What is on your wish-list?

Fullstack SWE here with some time on my hands. What tools/platforms/features are you missing that you wish were around & would pay a nominal amount for?

Some of my ideas to start the conversation:

1. Centralized and searchable resource location for research papers, institutional research, books, videos, podcasts etc.
2. Weekly roundup of news articles & new research papers
3. Cleaned and normalized tick data from multiple sources at the second/minute/hour/day level available via a REST API
4. "Chaos Monkey" back-test plugin which simulates API latency/downtime.
5. Back-testing tool available directly inside VSCode editor
