Future adventure mode will need a lot of new menus as there is a lot of possible professions, and many of those, such as lawyer, tavern owner, ruler, merchant or military commander are mentioned all the time in suggestions or requests.
Apart from new menus, many things should be done through dialogues - for example as a judge you preside over a case - in a courtroom, with witnesses, prosecutors, defendants, attorneys of all sorts etc. You preside by asking different sides to present their claims, give testimonies, present evidence and perform multiple other tasks - this will be easiest to do via dialogue - you ask sides to do something and they do it. Afterwards you could use the option to "shout" - as it is currently in game, but would as such work as a speech, in which you can choose whether the defendant is guilty or not, and then choose a punishment for him from the list of available ones. Afterwards you can order a court official to proceed - either to carry out the punishment, escort to the prison or escort out of the building and set free. I think that the player should roleplay the judge - he might have something like "evidence window" where those are described in detail, but he should mostly listen to what others are saying, and draw his own conclusions. Some character abilities can certainly help - such as judge of character - a dialogue can contain your character's opinion whether the speaker is telling the truth or not, which will not always be correct, and ultimately you would have to rely on your logic.
The same can be done with many choices the character has to make - leaders have to make choices every day, and they are approached by their subordinates who propose different courses of action. This could easily be resolved through a dialogue.
