Here is the description of the V3.0 interface. Hover its buttons to get a quick description.

Although you can use the plugin without it’s interface, doing so isn’t recommended.

1. Classic tile modifiers : rotate & flip. The “tile” icon shows you the tile’s current state.
2. Classic tilemap options
3. Options you normaly see in the Tileset menu : show tile hints and select next/previous tile
4. Hide texture list
5. Show classic tilemap dock if you don't want the new one.
6. When this is active, hovering a tile in the world canvas will tell you which Tilemap it belongs to
7. Notice those tools stay the same
8. Texture list, similar to the tileset interface
9. Tile selection panel
10. Show pattern list : allows to choose which pattern you're gonna draw with without using the Inspector. Plus, it gives a preview
11. Turn into pattern : [If you don’t want to write patterns, you can draw your pattern on the TileMap and selection it with the Selection Tool (not the standard Godot tile selection) and press “turn into pattern” in the Pattern Tool or on the TilePalette .](https://dark-peace.notion.site/If-you-don-t-want-to-write-patterns-you-can-draw-your-pattern-on-the-TileMap-and-selection-it-with--ab0093c0845a495f9151b73fb8bcfa9e)
12. Cursor list : allows to choose which extra cursor(s) you're gonna draw with without using the Inspector.
13. (Un)Select all cursors
14. Tilemap list : allows to choose which Tilemap you're gonna draw on without using the Inspector.
15. Allow to select multiple Tilemaps. Only useful when those have the same tileset
