The default pool in Bitcoin Miner is actually a multi-pool, where it has your devices mine whatever should get you the best yield that the miner supports, and then converts it over to Bitcoin. This is a fairly complex process as right now the pool pays per share, which means the pool carries all of the risk associated with crediting users up front in Bitcoin for underlying work performed in other currencies (exchange rate risk, risk when the pool has to issue payouts for credited shares when blocks haven't been found yet etc.). Listing found blocks in underlying currencies would be tricky, as it wouldn't have much meaning since blocks found in alt-coin X wouldn't make sense if your miner was mining alt-coin Y. There are several fairly complex calculations in this, but turning it into a user-friendly format that people can make assumptions against is fairly hard since it's tricky to show clearly:
1. How to correctly calculate the spot value of a share
2. Adjust #1 for exchange rate risk (see futures pricing)
3. Adjust #1 and #2 for any exchange fees the pool incurs
4. Do 1-3 on a per-share bases that is unique to each users based on their hardware configuration.

This is very different from most "dumb" pools where you only get paid in currency X if you're mining currency X, and only if the pool finds a block in currency X.

On GroupFabric's pool, you get paid in currency X, when you miner could be mining currencies A-Z, and are being credited in currency X regardless of whether a block has been found in currencies A-Z.
