Anyhow, think a Freemium pricing structure would go down well for this extension, so to fund your dev of a version that supports this to front-end editors could be based on a subscription/fee.
Great job & thinks on giving this free version to the community.
The quality of the extension and the support is really at the top of the game ... one of the best dev companies in the Joomlasphere.
Matthias is very talented and I love that someone has done a plugin like this. For anyone who has run WP blogs this functionality is a must for SEO.
Big bonus in WP is that the meta area is below the text, so a you write it updates the meta. J unfortunaely hides it invisibly on the right.
If Matthias can get it to refresh every 100 characters/30secs(??) and be just below the article area so we can see what keywords are being generated from our content then this would be an even bigger winner!!
Well worth the cash, great support, active dev, clients love it (even more with the new version).
