While some of the active users here are Calibre developers, there are also normal users around here. So development should be safe, I think.

(Also, if possible, please don't forget about my desired author and title like custom columns)

There's no need to include a link to that thread in every post you make. As you have noticed, the developers are active forum users, and if one of them is interested, they'll implement it. If not, you would probably have to do the work yourself. If you really fear you're being ignored, you might look into opening a ticket requesting the enhancement in the Calibre bug tracker.
