Hello Alex,
A few questions and comments....
(a) I am unclear as to whether Winboard engines will be able to use their own opening books or will all engines, UCI and Winboard, be required to use user created books in your gui?
(b) Do you understand that you have now created a situation which may lead to rioting in the streets? Do you have a beta for the bold and willing among us to try? I can assure you that one beta release is worth several hours of remorselss tinkering as the fans here will use your gui to do all sorts of unnatural acts....
Ooops, wrong forum but you do get the idea....
A beta release would be wonderful BUT by all means ignore this impassioned plea and continue to work at it. I will just have to wait.
(c) The idea of calling other programs within the gui is an excellent one for techno-phobes such as myself. That feature is appreciated already!
(d) Now, now, now, we must have it now!
Ah, sorry about that. That was the immature and impatient me. Nothing at all like me normally.
Later.
Ps. Looks really hot! Keep working....
