Couple of arbitrary ideas

Weather effects on the screen - I thought it would be cool if you had water drops / snow flakes show up on your screen during storms / blizzards. Could be an option to turn off for people who don't like extra cosmetics, or crafted goggles so you could see through it. I love the heat shimmer in the deserts and think there could be other effects.

Environmental slot on armor If you're going into a snowy area, you could affix furs to your armor (changing the cosmetic look as well) to get a +cold resist; same for desert / marsh areas with engineering / tinkered water systems / sealant systems, with resists to heat / water respectively.

Just random thoughts.

Yea I really love the detail they put in the weather systems and effects thus far (lightning reflection on water is awesome, as is the blurring of objects when it's foggy, etc). I just figured that little extra stuff that adds to the world is what makes it feel alive (moreso than it even already is). They've done a wonderful job making the world seem full of life thus far with the changes to the zones and stuff, but there's always room for more little things :D I had some other thoughts, but they elude me for now.

Oh now I remember:

Ticket system for player housing when it's done up like a shop - So I remember reading that we'd be able to open our player housing up like a shop for people to come visit and buy stuff from. I'm really hoping they'll allow mannequins to be created by carpenters or something so we can display the different armors we have for sale (or weapons, clothes, etc), but more than that, a system where people can submit a request to the crafter to have a piece (or set made) that would auto deliver it to them when finished. I know you can just go to the market boards and look, but for that immersion feeling, and to reward crafters who make good names for themselves, having a system that makes it easy to request from them would be cool.

I also hope there's an easy way to access the shops when housing is implemented. It's easy to go to the market boards and buy stuff, so I'm hoping a system where you can click on the retainer's name to visit the store will be put in.

Another small thing I thought about today while mining: Since a normal hit gives +5 gp and a miss gives none, would be nice if getting an HQ strike gave 10 gp :D
