Thread structure on the forum

I am not sure which posting of mine you are referring to, but its true that I often find it quite difficult to follow a longer thread with multiple forks and that I also find it hard to navigate therein.
I see at the top of each posting to whome it is a risponse to (which is helpful), but I would have to click that link to be directed to the very posting (which is not necessarily what I want as there is no way back to the posting I was just starting to read!)
I agree that there can't be a magic solution and indentations cannot be endless for obvious reasons.
I guess that part of the problem is, that the page design is not only wasting very valuable vertical space but also horizontal space.

There is a large white, mainly unused column to the right of the posting. So the room for the message bodies could take up some of that space (making the threads a bit shorter or the indentations better visible) and it would be possible to implement  a floating message tree in a column on the left of the bodies which could help significantly for easy and quick navigation in larger threads (not sure if Khoros offers that kind of element, it sure should).

I also would vote for more flexibility. The user should be able to switch on or off the aforementioned tree with a simple click as its not needed for shorter threads.

I also often have a problem finding the last posting in a larger thread which is already marked read. I know that I could set the flat view of all(!) threads in my personal settings but thats far too cumbersome to do. I would prefer a simple button in each thread where I quickly could change the thread view from indented to flat and vice versa.

Just my 2 cents.
