Don't like my hack, don't find it useful, don't install it. Fine with me. I don't know why you feel you have to come in here and say so though. I created this hack because people requested, so obviously not all feel as you do. When did we start going into others hacks and publicly criticizing them?

To ensure that you aren't going to be criticized, don't release hacks.
Just to point out, however, I did say that I find how this hack could be useful.

And then when you upgrade you have to re-edit all those templates.

That, once again, has nothing to do with plugins.

It is most certainly an opinion, not a 'fact'. The cost of a proper join is nearly non-existant, especially compared to the design and maintainence benifits. It's called a relational database because it's designed for related tables, not flat tables.

I am not going to argue about it, I am just going to say that in my opinion, creating an extra field for just one table is a waste.
