Tiles in the map editor are too small to make out

[Roseweave]

I really like the simplicity of the map editor - I like to use Dungeondraft myself but that's a lot more in depth. I wanted to give something to my DM to have something simple to throw things together, and this is perfect.

However, the thumbnails are absolutely tiny. They could be nearly twice the size as-is with all the white space around them.

I'd also consider making it easier to shove in tiles from PNGs if possible.

Thank you.
