A forum section would only make sense, if there were a lot of discussions about it.
Until then such things can and should be discussed in the generic section of the forum.
Also the forum is a place for users to discuss which each other. Sometimes the developers take part in this, sometimes not).
For improvement it needs "man hours". That is, at least one person that sit down and does the work.
If you want better result it is not as much a question of discussing it here, but to actually add "man" to the "man hours" (contribute)
From past experience the forum can lead to a person deciding to contribute, but often just leads to a long discussion with no real change in the end (sadly).
If you or anyone have an idea what they would change, and if you are willing to then provide a patch for it, then you can discuss it here or on the mail list to see if it will be acceptable.
Or you can supply a small demo patch on mantis, and add more if it is accepted.
IMHO if you have concrete plans of helping the best place to discuss it, is the fpc or lazarus mail list (depending what part you want to add to).
If you need help to understand the how the help system works and is edited, then ask here.
Of course you can also just provide ideas or talk here, and hope someone else will do it.
