Do you remember when there was no configurable key to select the nearest npc/mob?

Do you remember when headgear could not be hidden?

Do you remember when we didnt have keyboard shortcuts to start specific chats (like CTRL+L for linkshell)?
This leads to: do you remember when keyboard chat shortcuts were introduced but CTRL+R selected the last person we talked to and not the one a /tell was received from?

Do you remember when there were no macros (before second beta phase or something like that)?

Do you remember when you had to face a monster to start casting a spell against it?

Do you remember when a levequest difficulty could not be adjusted after starting it?

Do you remember when chat logs opacity could not be modified and we only had 1 chat window?

I could go on... :P
