There is a great chance of someone already mentioning this. It is even possible that what I want is already possible from the get go, making this thread useless. If that is the case: I am special!!! 
One of the things I would like to make for Elemental is the possibility of text adventures. Thinking only of single player, it would be in the line of Space Rangers 2 where you could take part of text adventures in different planets.
Basically, in adition to being able to wage war with the Dominators, trade stuff or kill pirates/merchants (being one yourself or not), these text adventures would take you to a different interface where you had a mission to solve and in which you were to take different decisions ("Do I use kneepads for my meeting with the guard or do I use my VISA Adamantium with him?") to acomplish your goal (like not dying if you were sent to jail!).
The problem with quests in Space Rangers 2 that made me forget about those text adventures is that most have some random elements into them, and you success or them or you die. I never finished the mecha combat adventures due to randomness, therefore I died everytime. Meh. Rewards were usually fame, money and maybe items.
Back to Elemental, we already have quest screens (I remember two types during Beta). Not sure how they work but I am going to suppose that to modificate them to open other quest windows based on the selection made should not be too difficult (once I get to know intimately all the agenst involved in summoning windows, creating buttons, functions...). Right now they show a text and offer you a couple of buttons.
The main idea would be to create many quests based in resolving one text adventure (or chain of but lets not get ahead of ourselves), in addition to the normal quests that can be currently created. That would be especially interesting for non combat quests. Because seriously, I want my fragile diplomat with adventurous spirit, be able to take part of some kind of adventures (random text adventure dealing with some ambassadors, for example). Or as alternative to the combat option of some quests. And it would be certainly interesting as recruitment option for some champions/monsters.
And as my focus is single player, those text adventures could be complex and/or long (to a point!). Not sure if some kind of option to save game in a middle of a text adventure would be needed or not. Space Rangers 2 did not use them and I missed the option a few times. I understand it "reduced" the "cheating" though.
Related to this, and considering that I have not been able to study Python ( and what I learnt is so rusty that is not worth mentioning), I was wondering if the main screen is modable too. You know, being able to add new options to the main menu. One reason I am interested in this is because I would like to eventually add a... er... Alienpedia/Monsterpedia/Winterpedia/*.* to the menu, so players do not need to start/load a game to check stuff related with the campaign/game world.
And also because I need to practice/learn Python so I have thought that focusing at the very beginning in creating a test text adventure (a mini "text adventure" mod?) in Elemental (not that I could not make it in a different enviroment like Pygame), I could familiarize myself better with windows, positioning, image swaping (maybe showing 3D models like the Diplomacy screen?*)... and that kind of stuff that right now is "WTF?" to me. Starting/loading the quest without the need to load all the other world stuff would surely be faster/better.
Yeah, another silly thread by yours truly, Wintersong. By now, only newbies (noobs, if that is your style of diplomacy) should be surprised. 
* that would go way beyond pure text adventure (unlike static pics) but could be interesting too.
