Binton, Ah the dock is a tad out of date. There is now a prexisting bit of code that reads
Code:
OnHide="Collapse.Activated=false Collapse.Checked=false"
Switch both statements to true if you want the window collapsed by default.
Insert
Code:
Shrink.Activated=true Shrink.Checked=true
if you want the window shrunk by default.
Make both changes if you want it both collapsed and shrunk by default.
Adding the include for Bagstrip to eq2ui_mainhud.xml should be all that's needed to get the Bagstrip working.
To update the pieces to look more like the current default UI requires editing the provided images and possibly a few text color tweaks. Nightfall Goth uses a silver-blue pallet. If you have Photoshop, you could fairly easily merge the blue elements in with the gold elements from Classic.
ATM, no it isn't possible to tweak the expanded background via window options. I may play with enabeling that, though there's hardly any background to hide.
