How to add grass back to an already modified area?

The sickle will cut grass which you can then use in your hot bar to replant it in areas. It won't automatically grow back in places where you cut it so make sure the place you're actually going to cut is an area you don't want it it.

Would be nice if the sickle would have 2 modes. Left mouse would cut grass and it won't grow back, right mouse button would cut grass but it will grow back over time. Or any other solution to only temporarely remove grass. Plus an option for admins to set grass growback time.

It's been tossed around a few times in discussions. Personally I like the idea of the grass growing over time. I think it could be cool to come back to areas after a long time and seeing nature retake an area. Even having it where you cut the grass and it gives enough to manually replant it plus a little extra (like what happens with tree saplings) would be nice.

Grass before was somewhat farmable if you kept placing it and using sickle on it.
Some recent update made that impossible now where if you place grass down, it consumes 3 of grass but when using sickle it gives back 1 grass.
The game needs some kind of bonemeal similar to MC where ti changes nearby dirt to grass or grass regrowing.

In creative F6 mode, there is grass to plant

In the Java version, we had grass seeds to scatter. With F5 in creative mode, you can paint the grass as high as needed. However, the grass seeds are probably better for survival mode.

The mown grass can now be used as grass seeds.
