Hello. I hope my idea is of interest...
Reminder.
Often playing every time, despite all the cases, I forget what I want to do now. I build plans, tasks and ideas. I get distracted and forget. I'm sure many have experienced this. Especially when playing with friends. I enjoy building, creating and experimenting so much that I forget what my friends need. They can remind me, but sometimes they forget what they wanted. To do this, at first, you can use the game chat. When you re-enter the game or load the world, all this is erased. That's why I need notes, bulletin board or whatever to help me remember.
How I present it.
Player Diary
The simplest and most banal thing that comes to mind is the player's diary. This is a regular diary that you can use during the game, make notes and easily edit.
Board with announcements
This is a board on which you can write notes. Just walk up, enter edit mode and edit. And also the same boxes with inscriptions. To be comfortable doing this job, the player needs to be able to read at some distance.
Let there be several types. 2x2, 3x2, 3x3 which can be placed both on the wall and on the ground.
Stickers.
Lots of stickers. I glue everywhere, always, for no reason, when I want.
Here are my ideas. I want to remember and know what I want now.
