SageUI Bags and INventory questions

[The Griffin]

I downloaded SageUI today, and overall I like it a lot -- it's really convenient, and I appreciate the design choices that went into it.

However, I have two problems:

First, the main inventory panel is waaaaay too small. I can't tell which slot is for what, and I have to squint to use it.

Second, the bags don't have any borders or background, which I imagine is useful for some people but it's driving me crazy. I can't tell where the slots are, and I can't figure out where to click to move the bags around.

So... how can I tweak the xml to increase the size of the main inventory panel back to the standard game size (while keeping all the extras), and how can I add borders and a background to all the bags?

Thanks for any help you can provide...
