Forum:A potential new page?

It seems as though a lot of episodes make reference to things that, at least as of right now, haven't yet been shown in another episode. For example, in Rollercoaster: the Musical, Doofenshmirtz makes a comment about how he really ought to finish the "Doofenshmirtz Evil Incorporated" jingle. Knowing the way they write the scripts, I wouldn't be surprised in the least if he actually does in a future episode.

Likewise, when Perry leaves Doofenshmirtz before he has the chance to talk about his scheme involving "eulg" because he needs to operate the robotic Lawrence in the I Was a Middle Age Robot episode, Doofenshmirtz says, "This will be a backstory, too, someday!" Again, I fully expect that to be a future backstory.

Does anyone think it would be beneficial to start a new page that just compiles all of the things that various characters say they want to do "someday" or "in the future" but which haven't actually materialized in a specific episode?
