Thanks!
Regarding the grid: do you mean just to add an ability to make it smaller (like in Procgen Mansion)? I can do that, the only problem is that a smaller grid will make maps even noisier.
Regarding the tags:
You can get some very short info about what effect each tag has by shift-clicking it.
I wrote about this feature in the release post when it was implemented, but it's not mentioned anywhere else. I will fix it by adding a hint text in the Tags window.
