Off the top of my head, maybe add a way to hold back x funds. For example, let's say I have 10 LTC in my account. I want to ensure I always have 5 liquid for whatever reason. I can set up a "strategy" that will ensure it will never invest more than balance-5, such that it will start by doing 5, as that grows, it'll do 5.1, 5.2, etc. If I throw in 100 more, it'd do 105.x, still leaving that first 5 behind.

I'm thinking about this in terms of liquidity -- it's nice to be able to lend, but would also be nice to have a little you can hold back. And to make it even more usable, allow you to hold back x% of the balance or x% of earnings, such that:

I deposit 100 LTC. I want to keep 50% of earnings liquid. So after a week, that 100 has earned 3 more. It's now lending 101.5, keeping 1.5 behind to liquidate/trade/whatever. For even MORE utility, have it swap those funds from the main wallet to the exchange wallet (or wallet of choice -- on each site) automatically so you can even keep the balances separate.

I can think of many uses for all of these scenarios, .
