whilst all trading is USD based, as you pointed out, however in realities for me, the value in GBP is more understandable/comparable, and as such i use your bitcoin gadget to display my wallet content, and it's value in GBP and then i use your other gadget to display the current GBP exchange rate.
I use the BitPay exchange api because one of the PC accessory sites i use accept bitcoin, and use that site for their conversion rates.
THe high / low rates being in GBP would just have been a nicety
oddly enough nobody does this, even the BitPay widget for your phone, that they make only ever works in USD yet their site is a global concern that supplies exchange rates in multiple currencies.
this is basically what i have on the screen....

leaving for the time it took to screenshot and upload resulted in it updating....
