I'd like to see the spread of grass and other biomes increased by at least 4x or more over the current speed. Right now, it's OBSCENELY AND RIDICULOUSLY SLOW. It's insane. The grass on my front lawn grows faster than this. And, if you aren't willing to increase the speed for god knows why, at least let us cultivate seeds to proliferate the spread different biomes. I filled my plot with trees, and it's barely over 50% filled with forest biome. And this has been at least two weeks of effort.

Here's another image that removes biome transitions and trees to better show how awful this is:

This problem is also super annoying if you have any roaming livestock who eat the grass around and leave splotches all over town that last for weeks. It's just incredibly obnoxious. I know I'm being a little OCD about this, but come on. It's awful if you're trying to make something look nice.
Also, judging by the second image, it looks like even less than 50% coverage.
“We still, alas, cannot forestall it-
This dreadful ailment's heavy toll;
The spleen is what the English call it,
We call it simply, Russian soul.”
An idea to consider:
Tedium, a Feature.
