Has anyone made a visual xml editor for planeshift?
I don't think so. This may be useful, but seems quite complicated to implement.
Is it possible to have chat buttons over 2 lines?
The ones for the chat tabs? Arranging the buttons in two lines should work fine, multiple lines per button is probably not possible.
I have an edited version of container file which works for forges and stock casting but not sacks as I get duplicate lines which makes it look like I get more slots but when you move anything on the duplicate line the line clears see below for pic and code.

PS#6002 to me, so probably not your fault.
Also is it possible to have different sized windows for different types of containers ie. the size below for stock casting and forges etc and a smaller size for sacks
I don't think so, but at least you can make them resizeable. Personally, I prefer large container windows without scroll bars. Yes, there is empty space, but at least you don't have to scroll for "hidden" content.
