My Previous Posts = Easier To Find (one's previous posts in a thread OR in ALL of PSD

In case (as usual?) the Title isn't clear enough:
If you're in one thread and you want to quickly/easily look over any/all of your previous posts there, is there a super-simple way to do/add this?

Similarly, if you want to see part or all of your entire PSD posting history, is there a super-simple way to do/add this? (Right now we have the option to see all the threads we've posted in; but, in many cases, that is far inferior than being able to see all of them (either within a range of dates or not) in "one place".
Thanx,
