i don't use the raider trees myself, generally. If you use them, baby trees are hardly an issue, I think.
About the closing of the crafting window: I doubt it's something i'll make happen. One use case which comes to mind is baking (e.g. cabbage crumbs) where you can only make a handful of items per inventory, but you have to make a ton of them altogether. No need to make it even more frustrating by constantly closing the window. I generally just put the crafting window in a corner (or even off-screen), and use the keyboard commands (enter, shift-enter). What specific use-case did you have in mind to close it ?
