mate, I'm not angry or getting this personal, as I'm a regular 30b user who a few years ago made a choice. I've invested money and time to get my instance of 30b up and running. Probably I will move on when crucial modules will lose support of Prestashop 1.6. Probably I will go for WooCommerce, but not for it wide plugins selection and WYSIWYG customization, but stability of support from payment gateways, carriers and any other crucial external service providers. IMO those things should determine platform of your choosing, not eye candy stuff.
all this stuff you are talking about should be addressed to current 30b maintainers. you don't look as a newbie but still asking questions about things those are not there. believe me, if 30b had a wide selection of themes and WYSIWYG editor, you would read/hear about it.
my 5 cents are just a general view how ppl are now seeing world. eCommerce software is a product as any other for example car. If you are interested in buying one, you study your options and decide to buy it or not. you don't go to manufacturer and yell at him to add something because you, one client per million want it. but when it comes to free software such demanding behavior is a standard.
is 30b the best eCommerce software around the web? for god sake - no. is 30b the best documented eCommerce software? it could be better. but available info is more than enough to make a decision to go for it or not. at least if you have a basic knowledge of web technologies and did your homework on what things will be crucial for you.
