Thanks for the suggestions and donations (good motivation for adding more features

).
My menu bar is plenty crowded already, so I agree on the size issue. I'll work on a way to configure the number of decimals. Configurable font size isn't quite as straightforward, so I'm not sure when that'll happen.
I'll also add an option to change what the displayed label is. And I'll add the option to show an arrow if the price has gone up or down since the last update.
On the note of "if price has gone up or down since the last update" - I personally don't see the point of this (comparing updates to a single other) since someone selling
BTC0.01 will change the "trend". If other's support the idea, then by all means go ahead, but I would find it more useful if it compared the behaviour of the market over an hour or more, which will start tapping into the actual trends of the market. Not sure how best to implement this in order to accurately reflect the 'trend', but it is food for thought, at least.
