Ok, I uploaded the container type windows as a seperate mod under the containers category.. This includes: bazaar, big bank, loot, merchant, container, give and trade windows.. works with the default UI - see the downloads section once it's available
Those windows are nice, but I don't care to modify them.. they should work with the UI just fine though, and if they use the default templates (which I modified for this UI) then they will even look like they belong..
.. most stand alone mods should work if they were coded correctly
