Annoying AI actions that are unnecessary and needs improving

Ever been annoyed by your opponent tapping and displaying each land they used to cast every spell?
Who really cares which lands they using. Just cast the dang spell already. And obviously, their lands are already on the field so we're very
clear of the lands they have.
In addition, simple annoying things such as during combat where the AI had to go through each combat phase although no creatures were
able to block the attackers nor any spells or abilities to prevent the damages caused.
Moreover, wouldn't it be much easier if permanents that produces mana auto-taps the same way as lands do. We have an option to
manually tap our lands so why couldn't mana-producing artifacts or creatures have duh-mode?
Anyone concur?
