Free version is just a demo

The free version is unusable. You can spend some hours to create your css.
Than you want to save and cannot, cause you have mistakenly used a pro field.
If this happens, you have to search where you use the pro field, or lose all your work.
This problem is known for years. Why it blocks saving, instead of showing a message and only save the free features?

And basic css like color is only in pro available. I would understand if features like shadows and animations are pro-only. But color? Really? This makes the free version useless.

And there is no licence for web agencys or freelancers available.

It could be a good tool, if pro settings would be hidden (or didnt block saving) and basic css like color are in free version availble.
