Discord & Tech Tree
I've never used Discord before and prefer the forum format use here or on Reddit. Is the Discord community active with easily accessed good content? If so, maybe i'll give it a try.
I see you can download a csv file of technologies from the modding page, but has anybody created a user-friendly tech tree?
The Discord channel is active and the community is very helpful if you have any questions or ideas that you want to discuss.
As for your second question, not that I know of.
