I have downloaded and tried WebsiteX5.
This is one of the best, easy, and simple website creators I've seen on the net. however, it seems it does not support RTL (for languages such Hebrew/Arabic) for templates.
Vertical menus are presnted on the left side only.
Horizontal menus "stuck" homepage on the left aswell.
This is the main issue with RTL, since text and images can be aligned quickly to right.

[editing CSS manualy is usless. App save & restore default settings each time you access the project]

Giving an option to place menus to the right , will be a great addition for many users and those who wont use WebsiteX5 cause of that.
