Just a couple of upgrades that I would like to see on the STEEM-ENGINE

Just bought some more PAL and I am already mining with some PAL miners too. Using Steem-Engine is very easy, but there are a couple of suggestions from me that would make using it much more convenient.

Some examples are:

1. History of my own closed and still opened trades
   When PAL came to Steem-Engine and I claimed mine, I instantly sold some. After seeing how much is PAL worth now, I really want to know for how much did I sell them at the start.
   Another reason I want this is that I have some orders on tokens that have 0$ 24h volume. Imagine a situation, where you forgot which tokens you wanted to buy and now you have STEEM locked in some orders because you can't find them.
2. Charts
   The market depth that Steem-Engine has right now is fine, but I would like to see some candles to also see prices from the past (reason above).
3. Claiming PAL, SPL and other tokens on the Steem-Engine
   If I am not mistaken you can claim the rewards from the miners on the Steem-Engine, but is this possible for other staking tokens such as PAL or SPL?
4. Add staked tokens to estimated value
   For example it's really weird to have PAL miners having zero value because they are staked. Does it make sense that staked tokens do not count towards your estimated USD value on the Steem-Engine? The way it is done now it feels like they don't even belong to you because they are staked.

Those are some of the suggestions that I think are currently missing from the Steem-Engine. Hopefully @aggroed will read them.

Thanks!
