Switching wallets - what do you with remaining amount in pool

I'm new to mining and have been mining into online wallets generally speaking.  Now that I am learning more, I've found that I want my coin in a local wallet.  Currently my XMR is going to a wallet on freewallet.  I'm changing around the fork to a moneruju wallet. 

So as far as pool mining goes, once I get the next payout, what do I do with any remaining balance that is lower than the payout threshold?  What do you all do when you switch wallets? 

For example, say payout is at 0.1 XMR, I mine to 0.11 XMR.  If that leaves the .01 XMR in my pool balance do I keep mining to try to hit an even payout number or something else?

I realize we are talking small amounts but hey, it all adds up.  I am fine donating it as well, just need to know how to do that.

Thanks
