Right.
We're sort of going for a hybrid of old-school-forum and Reddit/WIN-forums.
Adopting some functionality from the latter, for the sake of trying to improve the forum in some manner.
In this case, about the thread layouts, I was planning on asking the software developer who created the original customization to improve it for us in a few ways.
Adopting some more of the Reddit/WIN functionality. Such as being able to collapse the thread trees (e.g., the 'threads within a thread'), for example.
I was also thinking of asking the software dev to make it a user-choice of what the layout looks like.
The first part (adopting Reddit/WIN functionality) should be easier, the second part (making it user-choice) I have no idea. I can imagine how the second part would be done, which is a good start, though, I don't know what the actual coding of it would be like (i.e., easy or difficult).
