Built a free dungeon generator with a GM prep sheet - looking for feedback

Description

Hey folks,

I built a free, no-account dungeon layout generator that exports any dungeon it makes as a PNG. The thing that sets it apart from other generators is that every layout is one you could actually build. It runs on the same 2x2 grid logic as a physical terrain system, so it never places a wall or a room that could not exist with real pieces.

There is an infinite-inventory mode, so you can generate encounters of any size with all kinds of room configurations, no cap on pieces.

The part I most want feedback on is the GM side, which I just rolled out. The tool auto-tags every room it generates, lets you name each one and add encounter details, and lets you drop pins on the map to capture story notes. There are two export options: a GM version with all of that, and a clean player version for everyone at the table. Also - optional printer friendly version, too!

Full disclosure: Although the tool is connected to my terrain system, The Endless Depths, it is entirely free and works completely without the terrain.

I am still adding features aimed at pain points other tools miss. What is on your dungeon-prep checklist that no generator has ever given you? Tell me what is missing and I will put it on the roadmap!
