-Droppable tent that acts like a small house with bed or bedroll.
-Droppable fireplace (act as light), droppable items (placeables) to place in your house, droppable boat (dinghy) and spikes (enemies walk over them and you can too)!
-Place bought paintings in your home.
-Buy droppable furniture for your home and ship.
-Make a lager cart to hull more for a larger price. Slower cart when used.
-A buyable house in Gothway Garden (small and large choice).
-Being able to write text (like an in game textbox) on dungeon walls.
-Merchants can write letters of credit for you with a larger fee than a bank.
-Throwing weapons.
-More random names, more random NPC names, ability to add names you want.
-Writing on the map like vanilla Daggerfall except the writing stays even if you leave the (farm, city, town).
-Guards can use levitate when you levitate to run away from them. Maybe add an aura to show that the guards are using levitate. Add the cost of levitating to the court decision if you are caught.
-Give a better variety of goods/loot in stores based on level and luck.
-NPCs can disappear at doors of shops to give the illusion of them shopping.
-Hear the audio "Halt" if you are standing in a fountain. Not enforced of course.
-Training doesn't take 12 hours of rest to train again. Maybe a slider in the settings for user choice.
-Magic items don't break but can't be used at it's lowest condition until repaired. (Kind of upsetting for me when yesterday I lost my Mithril sword).
-Horses can come in other colors.
-Ability to go to "Orsinium Area" if you manually walk or ride there.
-Add banks to "Betony" and "Isle of Balfiera" because looting from dungeons can make a lot of money and you can get encumbered fast.
-Add new cities and towns to "Betony", "Isle of Balfiera" and "Orsinium Area" that are lore friendly but not noted in lore. (They felt really empty).
-A button for lighting a torch or if you are out of torches cast light if you have it.
-Slider for enemies sounds to be turned down. (Rats and bats 'em I right?)
-Random enemies for the first dungeon Privateer's Hold.
-Knock on closed gates to ask for them to open at night (for bad climbers). Auto close gates after entering the gates. Requires a good disposition.
-Bribe NPCs to give up better information. (Maybe use pickpocket hand on them and have a window pop up to ask for pickpocket or bribe).
-NPCs can say more than vanilla comments.
-Main quest notes are put in the Journal instead of being in your pack.
-Backpack item to give you more weight to hull stuff at the cost of walking and running speed.
-Shoe type give better or worse walking and running speed. Armor boots are normal speed/neutral. (Mostly to make shoes and sandles to get some love other than armor boots).
-Clothes (type/quality) can make people like or hate you. Example is if you are wearing fancy stuff you can approach a king or queen and "___x___" then wearing armor or low quality clothes. King and queen won't talk to you in rags. Approaching a merchant in fancy clothes makes them "___x___" or charge you more. Wearing rag like clothes makes merchants pity for "___x___" or less priced goods. Armor or "full armor with clothes" is neutral.
I had much more suggestions but I forgot them at the moment. I will add more if I can remember. Hopefully some can be implemented into the game.
I will look around more and maybe I can find a way to help out too.
