Re: [Scidvspc-devel] Patch1: Eval bar for boards, inturn Enabled for Analysis Board

[Steve A <ste...@gm...>]

Yeah, it works under Linux, so not sure of the problem on macOS.
Nice looking eval bar :)

But like i said... it's value in the mini engine board is ok, but not a
deal breaker as you have the numbers there anyway/
And it's totally chaos trying to attach something like this to most normal
boards .

I'll see if i can get my eval bar working on *any* engine sometime these
hols.
Maybe you have some ideas about if it should be handled by some other
algortithm rather than just +-5
S.A.
