I'm not sure about a bug or maybe it's already reported but it's strange

Hi.
I’m not sure if they’re bugs but they’re things that seemed strange to me.

In this video:
1 - When clicking on “Export Tileset” the new window that opens says “Export sprite sheet” that’s strange, it confused me because I clicked on “Export Tileset”.
2 - In order to export the tileset I need to activate the “Open sprite sheet” option, why?.

im pretty sure its because you checked the preview box.
