I remember #11.... many of the other suggestions require a custom html editor to replace tiny mce or fkeditor. Wordpress comes to mind as they offer the same features.
Building our own cms systems still has advantages mostly for CRUD pages in inventory systems. Bootstrap foundations and the latest MySQLi behaviors really creates an efficient means for achieving similar goals.
The actual generation of new pages seems useful though a URL Rewrite rule coupled with. Single page using a url parameter can handle most of theses cases.
It seems our competition theses days is wix and squarespace and of course Wordpress though tools to integrate WebAssist pages into a Wordpress site would open up a world of benefit. Leave Wordpress for what it does well and somehow integrate WebAssist for our custom pages sharing the same theme. eCart integration into Wordpress would be an example.
