I like that it's an open-source software, with many functionalities to choose from (it has more than 30 plugins).
It is also easy enough even when you have no previous experience in web design or development; they offer simple instructions so anyone can use this tool without problems! The only thing which could be improved would maybe include some templates of layouts already ready made at first sight instead having users create their own ones using drag&drop technology - but as said before there are tutorials available online if needed.- A nice feature about these kind of tools/programs where everything works together seamlessly:- You don't need any knowledge programming language such PHP etc.; all work perfectly well by just typing commands into your browser console window while testing out new ideas / features during early phases of website planning stages ;-) This way we get feedback very quickly what exactly should change next time around until final results meet our expectations.
