What I'm asking is if there's a way that we can save post or pin or keep post some weeks can attend to them easily in the future.
There are replies that I have come across that were informative with things I'd like to go back to since the mY brain isn't trustworthy.
Hmmm. I found no similar functions even on some available scripts, i can only think is saving it on notepad which you already mentioned and is not a help for you, or maybe just bookmark the url/page for the meantime.
If the draft page also saves the URL of the reply/text where to post instead of text only it could be a big help, although you can manually check it on topic and msg id on the draft.
