Apart from what "Slow death" mentioned (#2 and #3), can we see a document/license in regards to this?

1. While changing the currency from BTCitcoin to Ethereum, a simple refresh will wipe that preference (you have to choose it again).
2. Noticed some irregular price updates, what's the time interval between those?
3. While choosing the price range (moving the slider), it's a bit hard to guess if the range is from "1" to the number being shown under the slider block or from the slider block number, up to the last shown value. Although this isn't a bug, I think instead of the number 1 value that pops in the beginning (after moving the slider), there should be the number that's being shown under the slider block.
