Hello,
Welcome in Chronicles of Arcadia!
TUTORIALS
- You can see all organized in Game Guides frame, accessible from either: F10 (default) or from ESC menu. Here you can also decide if you want to get some tutorials be marked as completed or no, so they can popup later.

- You can adjust settings how tutorials popup in ESC > Settings > Interface > Tutorials.

- Idea of colors for priority is nice and will be added to our to-do list.
- Would Game Guides frame be enough for your issue of Disenchanting or do you think it's still worth to add Pin? Worth to mention that there is Minimize button that should also ensure icon stays above chat right now.
MAP PLAY
- There is quite lot of various addons affecting world map to which I guess you refer, so telling their names as well as features you use from them the most, might be helpful. Some of them like DungeonLoots, WoWMap POI or QuestHelper might be considered heavy for some users and implementing them fully might be not something we would like to do, but if you point exact features, we can consider implementing them natively indeed.
- Follow arrow I think you got already solved with help of Brontes.
TWO STARTING GUILDS
- This idea is interesting, but currently not considered to be implemented, as based on our statistics, there might be not many players interested in this from among Newbies, and would contradict with idea of gathering new players in one place for easier finding of similar adventurers.
WORLDHELP
- Currently Megaphones are given out in Newbie Packages of different levels, but it might be not enough for some players.
- Your idea is interesting and might be considered in future, or otherwise increasing amount of Megaphones accessible for Newbies.
LOGIN SCREEN
- You must be referring to Assistant frame. You can find it either via shortcut U (default) or at Gear icon dropdown "Functions" in bottom right of screen:

We would be happy to get more feedback from you, as it's very valuable to get it right from community. Also activity with good suggestions might allow you to obtain some Reward Coins (worthful as diamonds) at Activities page.
Have fun exploring Taborea once again!
Greetings
