The item you are hovering over is highlighted by the brighter font color. The item you have scrolled to is also highlighted by the brighter font color, but at the beginning it is also highlighted by either having a bigger font (inventory) or by having a little icon next to it, indicating that it's selected. Unfortunately, these can become detached, and you'll suddenly only have the brighter font color to indicate what's selected.
No, there aren't. The only sections available are 'Chest', and then your personal inventory.
To begin with, you have to select the chest before you can take everything out of it. If you select the chest, you most likely have the intent to take things out of it. If you go into your inventory, you'd likely have little need to take things from the chest from there - and if you did, the chest is only a few presses or a click away.
I have no idea what it is you're trying to say here.
Maybe Bethesda should make that an option.
Or you can make it so the take/store button is never the 'use' button and allow people to use items directly from containers. Having the Take button be the same as the Use button, and the Store button be the same as the Take All button, is simply bad design. I very, very frequently go into a chest to sort things out, store a bunch of stuff, and then go back into the chest to grab one thing I accidentally put in there - and then take everything in it. Hugely annoying. The game shouldn't be designed in a way where this happens all the bloody time.
The inventory menu does tell you the item's stats. All it tells you is the item names. You have to scroll over the item to see stats, and even then it only shows a minimum number of them; weapons have more stats than just 'damage', 'weight', and 'price'. Further, the spell menu should tell you what the spell does when you double-cast it.
Yeah, but you could just press a modifier key to have it equip stuff in the left hand, and leave it as-is to equip stuff in the right.
I changed the Favorites menu to Mouse Button 4, rather than the default 'Q'. I suppose this might be why I can't close the Favorites menu by pressing the button again, but it's still bad design.
