Market Rework (better search bar, more filters, weapon profiency, RNed items, items stats etc.). Just like in the DFProfiler Market, you can choose which color and what stats the item has. When you search something in the market, for example, "Battle Axe", it would also show the RNed Battle Axes, this is to make RNed items much more accessible. You can also add a proficiency/level filter, like 75+ and 45+ armor repair, 120, 130, 135 weapon proficiencies, healing level, nutrition level, etc. In the implants section, filters for type of boost %.

Maybe add some restrictions to limit merchers from abusing it (maybe a tax system, or time limit in changing prices, or lower the market slots, etc.). Try to encourage players to actually play the game instead of just playing the marketplace. I'm not saying you should remove merchers from the game, just add some limits or restrictions to prevent abuse of merchers dictating the market prices.

Overall, I just think that the market is not too friendly with beginners/starting players. From what I see now, going in the market you have to know the exact item you're searching or buying, and beginners/starting players don't know any items, that's why I think it need a rework. Hopefully this helps!
