It would be awesome if the Dragonborn can leave letters after quests, on certain locations. For example:
-After infiltrating the Thalmor Embassy, behead Rulindil and the rest of the Thalmor Agents, place their heads on the table while placing their bodies inside Etienne's previous cell,
-After killing Deeja for betraying you,
-After sneaking into Calcemo's library,
-After the thievery jobs for Delvin and Vex, and many more
The Dragonborn will leave a note, with some message as to why they were killed/stolen, as if it was the Dragonborn's M.O just for immersion and role play purposes. The letters are custom made, where you can type the words just like the TAKE NOTES MOD but you can leave the paper on the scene.
If only I knew how to make a mod but it will really be awesome if there is.
