Disable a live Tagul for more Tagul clouds?

I see we can only have 10 live Tagul word clouds. Is there a way to disable some in order to create more as a user needs them?

I can see that many would like more. I'm also wondering, looking over the features of your word clouds, if people would like a way to pay. It seems word clouds have hit the education community deeply.

At first I have recently extented clouds limit to 20. The second, you can delete unused clouds and create new ones instead of them.
