update of wiki/documentation for all features of TSM4 (and archive TSM3 docs)
While you might find what you need in some of the video guide and discord can be helpful for immediate feedback (sometimes), TSM4 could really benefit from a bit more documentation on all the small features (and specifically how they work) that go beyond just creating a custom price.
Perhaps open up the wiki to your core group of help/support we see on discord so you have a lot more editors to help since I am sure there's a lot more coding that probably takes priority.
For many of them, there's probably already an answer in discord that could just copy/pasted in.
Also -- given there is no more support for TSM3 it would seem that these docs could get moved to a separate location, so that current users of TSM3 don't lose this information, but at the same time it doesn't get in the way of TSM4 users trying to find the information.
