"Wish List" for Springsharp

Top on my "Wish List" for Springsharp is better power calculations for small, fast ships like destroyers. Next on my list is to have some other mechanism for setting power per machinery weight other than setting the machinery date. The British super destroyer Swift, designed in 1905 was able to achieve a peak power output of 60 SHP/ton of machinery. The British Arethusa class light cruisers designed in 1912 had a power output of 40 SHP/ton of machinery. The power output of the Swift probably can't be reproduced in Springsharp, even with a 1950 machinery date. I would still like the ability to arbitrarily set power for machinery weight, perhaps with an indication of just how radical the figure that I choose is.
