Starter addition influence on ABV and SG

[amadest]

Hi. I have a proposal for one feature.
At the moment if you tick "Add starter to bottling volume" there is no influence on SG and ABV. In case of "small beer" this is ok, but for example in case of BGSA with SG 1,077 and 4l starter this quite a big difference (1,077 vs 1,069)

There is the dilution tool which can be used to determine the effect of addition of beer, wort, or water to an existing wort.  That would give you the effect on OG.

To your point, the information within the recipe for starter volume and gravity could be used with the brewing data to give you that information right up front.  Would definitely be a useful feature to be added.
