https://baza.cn.ua/admin/shop/products/exchange-xls/Is it possible to get through this (column "Availability")?
If not found, then no.
It didn't offend me at all. Your right to think whatever you want, my right to react to it or not.
I see no point in wasting my time explaining to you the historical aspects of product architecture formation.
In OneBox OS, the architecture has changed dramatically, which is why recalculations work faster and differently.
You have the right to change anything. Though by own forces, though by forces of integrators.
Similar to the answer above - I see no reason to waste time explaining to you why one functionality is there, why there is no other, why it works this way and not otherwise, etc.
In our product, everything works as it was implemented by us for one reason or another. If this does not suit you, you can either not use it, or use it as is, or modify it for yourself with the help of integrators.
If you want to demand something in the form of improvements / investments from us - please switch to OneBox OS, become a cloud user and you can offer your "ideas" similarly to other users on the forum - the conditions are equal for everyone.
