But there is another problem: blitter in Falcon is integrated inside Combel?

I will need time for "select blitter according to model"...
@1st1
it can be complete separate feature so someone else could implement it. Beside there should be automatization for creating "source XLS" file based on HTML, otherwise I would end up with maintaining two versions: HTML and XLS. I have a felling that this feature would complicate entire project x2.

First I should find some good javascript for sorting, filtering and searching tables...
