0) The BG1 forum is still alive you know. Use the menu in the bottom right.

1) No real effect, the game dosent much care. It would be cool if the seasons changed and all that, but that would be very hard to do in the infinity engine.

2) The game is old, certain of the scripts lack subtelty. Get caught pickpocketing, and everyone goes hostile. If your not getting caught, its probably a bug.

3) If you installed the BG:trilogy mod from teambg, you would be running in the ToB engine and could use TAB highlighting as normal. But thats a very large download and is a bit buggy still. IN normal BG1, there is no way.
