yep, sorry reading my post back i was perhaps a little harsh and it is an alpha after all.
I think you will find a lot of modx users are web designers, not developers who just want a simple to use CMS for ourselves and our clients - 0.96 fits this bill almost perfectly. If the interface had been like revolution to be honest i would have carried on looking (i have made over 20 sites with modx now)
I think my main problem is alpha 4 throws away a lot of structure, i know the good old file & folder metaphor is not fashionable these days but it = simplicity.
with regards to the site settings, if things are grouped by area anyway why not have permanent links to these areas at the top anyway? I don`t like the way you have to guess which page the setting you want to change, is on.
