Will the wallet get coin control features?
No is the short answer. Which is to say not in the near future. But if the community concludes that a hardfork is needed then yes coin control will certainly be one of the add-ons.
Right now there are two versions of the wallet and they work well. Minting is as easy as clicking the unlock button. And the wallet states current minting difficulty (so you already have a way of estimating your coin control standing) ... if you have mature coins then you should mint a coin rather quickly.
Bottom line if it not broken don't try to fix it. This said, I have played with over 60 staking wallets. The majority of them do not even connect to the network. The dev that replaced/fixed ver1.4 with the current ver1.5 demonstrated good grasp of pure stakes coding (early in the game mind you).
The wallets work and is as good as most of the more popular stakes coins and much better than many of the hack job pure stacks that are (ninja mined) rushed out to be pumped and dumped.
BCC has been over looked because it lacked HYPE. The dev has left a working coin in control of the bitcointalk community, it is not an abandoned nonfunctional coin.
Instead it is a fairly good coin lacking an active buzzing community. In part because it has no exchange listing known yet. That could change quickly. And all you that still have your original allotment of BCC best be staking!
@MarSas post you addie ... and I'll do my part to make sure no question goes un tipped
