I've seen more than once that the same suggestion is brought.
Why not creating sub-folders under each forum folder (I'm mainly thinking about the Suggestions forum), where each sub-folder will be a sub area?
For example - "Trades", "BB-Mail", "TL", etc.
In addition, using an index at the opening of each of those (sub-folders) pages will assist to easily navigate to the right thread.
For example, when entering the "TL" page, one will see all the links and names of threads mapped to that sub-folder.
Than, he can use those links to enter the correct one.
It sounds not to hard to implement and will assist a lot.
[In addition, I think that the Minor-Suggestion thread should include this kind of index as well, at its first message]
