For the ore dictionary you mention, if you click on an item that has multiple recipes, you have the option to scroll through the available recipes (should show a recipe count in the middle of the crafting table) which will then update the top crafting slots to show you what is required.
As the number of craftable assets increases, I will look to add a search filter which will make it easier to find things, as it may not be immediately apparent which section a particular item actually resides under.
I'm still working on a way for people to contribute content and information to the site, which will hopefully make it easier to update in the long run.
The crafting tree is a good idea for a future update. I'm guessing you mean that, should you want to craft a torch for example, it would show you that 4x torch = 16x sticks = 4x timber = 1x trunk (but obviously shown in a hierarchical tree view).
