Alright, let's get crackin'.
Here is
Sylvannor Trees and
Detail Trees, if that's the specific 'nice looking tree add-on' you're talking about.
Here is the
Advanced Roads pack, not sure if this the one you want though.
Control player mod, comes from my google drive since the link for the client control is dead.
I'm not so sure about the brick packs, I guess someone else can help you find it.
Edit: For my preferred add-on I love to use, I recently got
Blockland Essential's eventing tools as a separate add-on, thanks to Jes00.
I may list some more in the future later on.
