After getting requests for years, I am finally adding support for custom notes in Shattered Pixel Dungeon!
You can make plain text notes, or attach them to a dungeon floor or item. These are a great way of keeping track of information between play sessions, or deduced properties of unidentified items. Custom note titles will even appear in the descriptions of their items!
(Image Description: An image showing the various UIs for adding custon notes. A selection window for adding them is shown on the left. A cropped window is on the top-right, showing five custom notes in the adventuring notes UI. Another cropped window is in the bottom right, showing a custom note appearing in an item's description.)
Looks like no more need to switch to a notes app, this is wonderful
